With 10 million Java developers across the globe and 60 billion active Java virtual machines, of which 38 billion are on the cloud, Java is arguably one of the world’s most popular programming platforms.

Under the stewardship of Oracle and the open source community, Java hit a key milestone recently with the launch of Java 19, which features key improvements from OpenJDK’s Project Amber, Project Panama and Project Loom, among others.

Chad Arimura, vice-president of Java developer relations at Oracle, said Project Amber, for example, is a language level feature that was built to support emerging software development trends.

“People are building applications closer to the data boundary and they are taking data in through JSON [JavaScript Object Notation] or an API [application programming interface],” Arimura told Computer Weekly. “They’re doing some data manipulation on that and they’re spitting it back out and the programmes are getting smaller.

“And so, the things coming out of Amber are really looking at those patterns and saying: how can we make the language more concise? How can we help you model data more? How can you write code that looks like what’s in your head and does what you want it to do in a secure, efficient and performant way?”

Project Loom is another major feature in Java 19 that lets developers build applications in a scalable way, without having to choose between building performant code or code tha is easy to monitor and debug, sais Arimura.

“A lot of developers have had to turn to synchronous programming or reactive programming, and we feel like that choice doesn’t need to be made,” he said. “Project Loom introduces virtual threads, which is incredibly scalable, and you get millions of virtual threads that run on top of what we call carrier threads or essentially operating system threads.”

With more big data applications being written in C and C++, there is a growing need for Java to interface with those applications, which Project Panama was built to address.

While Python does a good job of wrapping C code, making it easy for developers to interface with big data libraries, Arimura said the way to do that today in Java is to use the Java Native Interface (JNI), which was developed a while ago.

But JNI was intentionally designed to make it difficult to establish those interfaces, he added, because developers at the time didn’t think there would be a need to interface with non-Java code.

“That’s different today because there are many choices out there and a lot of machine learning is built for very fast performance with C,” said Arimura. “So, Panama aims to resolve that and make it much easier, but also secure, safe and efficient.”

Java 19 is the 10th release of Java’s six-month release cadence, an effort to bring the programming language up to speed with the evolving needs of developers and the technology industry.

“After 27 years, nobody on the Java team is sitting back and letting things ride into the sunset,” said Arimura. “We are very active in making sure that the platform is ready for the next sets of challenges that developers face.”

That doesn’t mean pushing new features through without regard for stability. Features in projects such as Panama, which are not tied to a specific Java release, undergo extensive testing by the Java community, culminating in multiple incubator stages and previews.

The move to decouple feature engineering projects from Java releases was intentional. Sharat Chander, senior director for product management at Oracle, said: “As we all know in engineering, when you start developing a feature, through that course of development, you encounter issues and challenges that you may not have thought through.

“However, when you’ve made that commitment, you are forced to make compromises, not just to the feature but to quality, and so we’ve got out of that world of binding features to a specific release. In fact, by approaching features as large projects where we have incremental delivery, we are able to accelerate the stream of innovation.”

Over the course of its existence, Java has been declared dead on multiple occasions and accused of being in maintenance mode as newer programming languages emerge. Still, it has defied those assertions by looking to the future, figuring out what works with other languages and how they fit into the Java platform.

Chander added: “One of the advantages of Java is that we get to see what other platforms have done and learn from them, but it’s also about being complete. We want to ensure the functionalities meet the wide spectrum of needs across industries and use cases.”

Killexams : Lip with the kids

Hamline’s annual Lip Sync Competition brought the heat adding this traditional Homecoming touch this fall.

Sena Ross

An electric energy filled the air as the crowd flooded into the Anderson forum. 

The night’s host, drag queen and alumni Erin Bougie stepped onto the stage to introduce the lip-syncers. This commenced the annual Hamline Lip Sync Competition, a long standing tradition among the festivities of Homecoming week. 

Students have the opportunity to show off their talents and earn money in the lip syncing competition, with the winners receiving a monetary prize of $200. 

Each contestant chooses a song and makes up a routine to perform along with it.

Lip Sync competition winner junior Katie Mikesell mentioned their inspiration for performing and expressed enthusiasm about winning the cash prize. 

“I have a huge passion for burlesque, especially queer burlesque and I thought that I could bring something today. And also, I’m very poor and I wanted to win,” Mikesell said.

Mikesell expressed having plans for how they wanted to spend the money, putting it towards a future expense for their education. 

“​​I’ll put it in my savings account, get a passport so I can study abroad in Thailand. There’s a photojournalism opportunity for this J-Term. I’m going on that. I’m very excited about that. I haven’t gotten my passport yet, and I’m also unemployed right now,” Mikesell said. “I have been feeling this fire in me to perform, for sure, but there’s not a lot of platforms, and so I felt like this is a really good opportunity.” 

When talking about their performance, Mikesell referenced queer ballroom and drag culture as driving forces behind their creative choices. Especially referring to the type of music and dance common in these communities. 

“It’s the type of burlesque drag that I want to emit as a performer, so it’s very, like, sexy, old Hollywood, and I’m also paying an homage to all of the Black women who have (as a white woman I feel like that’s the least I can do) given so much to the jazz community and to burlesque, period,” they said. “I felt that kind of, like, channeling their energy to deliver something new and beautiful. That’s kind of what I wanted to do. It definitely was kind of its own thing.”

Sophomore Annika McClintock attended the Lip Sync Competition, and talked about her expectations before the performances. 

“I am expecting some comedy, some drama. I’m expecting a very good performance. I heard they go all out,” McClintock said.

Senior Essence Boe performed as Cat Valentine from “Victorious.” (Sena Ross)

After the event, McClintock felt that the performers put on a memorable show and that the best parts were the comedic stylings of several acts. 

“I very much enjoyed it. It was so funny. Like, my eyes were watering at one point. I was not expecting it to be that entertaining. My favorite was the ‘Call Me Maybe’ one. I was just not expecting that at all, and it threw me off, but in a good way,” McClintock said.

Competition judge and Director of Student Activities and Leadership Patrick Haught talked about the format of the judging, and the parameters in which performers are graded on. The Lip Sync Competition has a number of performers, but only three will take home prizes at the end of the night. 

“There’s four categories that have 10 points each. The categories are originality, lip sync-ability, appearance and crowd reaction. Crowd reaction is probably the easiest to tell. I try to capture as much of that as I can in a performance. I also try to think of who’s thinking outside of the box,” Haught said. “This is my second year judging it and the two years before I planned and coordinated it, and then shifted it over to the students and the programming board.”

Killexams : Oracle Releases Java 19

New release delivers seven JDK Enhancement Proposals to increase developer productivity, Excellerate the Java language, and enhance the platform's performance, stability, and security

Java 19's key capabilities to be showcased at JavaOne 2022 in Las Vegas on October 17-20

AUSTIN, Texas, Sept. 20, 2022 /PRNewswire/ -- Oracle today announced the availability of Java 19, the latest version of the world's number one programming language and development platform. Java 19 (Oracle JDK 19) delivers thousands of performance, stability, and security improvements, including enhancements to the platform that will help developers Excellerate productivity and drive business-wide innovation. Oracle will showcase the latest capabilities in Java 19 at JavaOne 2022, taking place October 17-20 in Las Vegas, and via a keynote broadcast airing on dev.java/ at 9:00 a.m. PT on Tuesday, September 20.

(PRNewsfoto/Oracle)

"Our ongoing collaboration with the developer community is the lifeblood of Java. As the steward of Java, Oracle is steadfastly committed to providing developers and enterprises with the latest tools to help them create innovative apps and services," said Georges Saab, senior vice president of development, Java Platform and Chair, OpenJDK Governing Board, Oracle. "The powerful new enhancements in Java 19 are a testament to the monumental work across the global Java community."

The latest Java Development Kit (JDK) provides updates and improvements with seven JDK Enhancement Proposals (JEPs). Most of these updates are to be delivered as follow-up preview features improving on functionality introduced in earlier releases.

JDK 19 delivers language Improvements from OpenJDK project Amber (Record Patterns and Pattern Matching for Switch); library enhancements to interoperate with non-Java Code (Foreign Function and Memory API) and to leverage vector instructions (Vector API) from OpenJDK project Panama; and the first previews for Project Loom (Virtual Threads and Structured Concurrency), which will drastically reduce the effort required to write and maintain high-throughput, concurrent applications in Java.

"Java developers are increasingly seeking tools to help them efficiently build highly functional applications for deployment in the cloud, on-premises, and in hybrid environments," said Arnal Dayaratna, research vice president, software development, IDC. "The enhancements in Java 19 deliver on these requirements and illustrate how the Java ecosystem is well-positioned to meet the current and future needs of developers and enterprises."

Oracle delivers new Java Feature releases every six months via a predictable release schedule. This cadence provides a steady stream of innovations while delivering continuous improvements to the platform's performance, stability, and security, helping increase Java's pervasiveness across organizations and industries of all sizes.

The most significant updates delivered in Java 19 are:

Updates and Improvements to the Language

  • JEP 405: Record Patterns (Preview): Enables users to nest record patterns and type patterns to create a powerful, declarative, and composable form of data navigation and processing. This extends pattern matching to allow for more sophisticated and composable data queries.

  • JEP 427: Pattern Matching for Switch (Third Preview): Enables pattern matching for switch expressions and statements by permitting an expression to be tested against a number of patterns. This allows users to express complex data-oriented queries concisely and safely.

Library Tools

  • JEP 424: Foreign Function and Memory API (Preview): Enables Java programs to more easily interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the Java Virtual Machine [JVM]), and by safely accessing foreign memory (i.e., memory not managed by the JVM), this API enables Java programs to call native libraries and process native data via a pure Java development model. This results in increased ease-of-use, performance, flexibility, and safety.

  • JEP 426: Vector API (Fourth Incubator): Enables superior performance compared to equivalent scalar computations by expressing vector computations that reliably compile at runtime to vector instructions on supported CPU architectures.

Ports

Project Loom Preview/Incubator Features

  • JEP 425: Virtual Threads (Preview): Dramatically reduces the effort of writing, maintaining, and observing high-throughput concurrent applications by introducing lightweight virtual threads to the Java Platform. Using virtual threads allows developers to easily troubleshoot, debug, and profile concurrent applications with existing JDK tools and techniques.

  • JEP 428: Structured Concurrency (Incubator): Streamlines error handling and cancellation, improves reliability, and enhances observability by simplifying multithreaded programming and treating multiple tasks running in different threads as a single unit of work.

Driving Java Innovation in the Cloud

The Java 19 release is the result of extensive collaboration between Oracle engineers and other members of the worldwide Java developer community via the OpenJDK Project and the Java Community Process (JCP). In addition to new enhancements, Java 19 is supported by Java Management Service – an Oracle Cloud Infrastructure (OCI) native service – that provides a single pane of glass to help organizations manage Java runtimes and applications on-premises or on any cloud.

Supporting Java Customers

The Oracle Java SE Subscription is a pay-as-you-go offering that provides customers with best-in-class support, entitlement to GraalVM Enterprise, access to the Java Management Service, and the flexibility to upgrade at the pace of their businesses. This helps IT organizations manage complexity, contain costs, and mitigate security risks. In addition, Java SE and GraalVM Enterprise are offered free of charge on OCI, enabling developers to build and deploy applications that run faster, better, and with unbeatable cost-performance on Oracle Cloud. 

Underscoring Java's popularity with the global developer community, Oracle is proud to recognize the one millionth completed Java certification. Java certifications help developers stand out as Java experts and raise their profiles with enterprises seeking to attract highly skilled Java professionals.

Killexams : ‘We don’t teach developers how to write secure software’ – Linux Foundation’s David A Wheeler on reversing the CVE surge

Teach devs security fundamentals to bolster supply chain resilience, argues Wheeler

Coding school

Addressing a decades-old deficiency in coding curriculums could have a profound effect on the security of the software supply chain, a leading expert on the subject tells The Daily Swig.

In particular, David A Wheeler, director of open source supply chain security at the Linux Foundation, draws a link between a failure to incorporate security into entry-level developer courses and the vast majority of vulnerabilities belonging to a small number of common bug classes.

The IT PhD and Certified Information Systems Security Professional (CISSP) also moonlights as adjunct professor of computer science at Virginia’s George Mason University, and in 2020 concluded a 33-year spell at the US Institute for Defense Analyses.

Daily Swig: David, can you summarize your background and what your current roles involve?

David A Wheeler: I’ve loved computers since junior high school and paid my way through school doing computer consulting. I also briefly maintained the world’s first commercial, entirely text-based multiplayer roleplaying game, Scepter of Goth.

Now I teach at George Mason University on how to develop secure software – which I’ve studied over many decades.

Most of my work is with the Open Source Security Foundation, OpenSSF [whose members include AWS, Google, and Microsoft]. I view my role as being a kind of catalyst or accelerant. I can run around as a subject matter expert to help organizations Excellerate the security of their software.

David Wheeler, The Linux FoundationDavid A Wheeler has studied the secure development of software for decades

DS: And what are the biggest barriers to improving application security?

DAW: The fundamental problem is that we do not teach software developers how to write secure software.

I don't care if it’s a separate course or embedded [in other coding courses] – that's not the question. The question is: when software developers are learning the basics of their craft, do they learn the basics of developing secure software? And the answer is mostly “no”.

A 2019 Forrester study found that none of the top US coding schools and none of the top five non-US computer science schools were teaching this. Another study found that only one school did – at UC, San Diego. So good for them, shame on the rest.

DS: Let’s imagine all coding schools immediately revamped their courses to incorporate security fundamentals. Would we see a steady fall in vulnerabilities as a new wave of security-savvy developers emerge?

DAW: It’s generally estimated that somewhere between 90% to 95% of all vulnerabilities are in a relatively small set of common ones [classes].

So, if you educate developers to prevent them systemically, and then use tools to find the stragglers, we can dramatically reduce by at least one order of magnitude – and maybe two – the number of vulnerabilities that actually slip out.

They can also find and fix the problems created in the past.

Right now, detection, response, and recovery is overwhelmed by the sheer number of vulnerabilities going into deployed systems, so it will be much easier to counter the attackers when vulnerabilities are much rarer. And that's really the argument of ‘shift left’ in general: the sooner you can get rid of the problems, the better.

DS: Why is security neglected in the coding curriculum given the potentially severe consequences of software vulnerabilities?

DAW: Our educational system does not always respond to societal needs. There was an open letter written by Oracle and some other folks 10, 15 years ago or so, where they basically begged universities [to educate them properly].

But sometimes they [universities] want to teach what they want to teach, and it doesn’t matter what society’s needs are.

DS: Could this partially reflect the fact that many educators learned their craft when cyber threats were less numerous and severe?

DAW: On the [early] internet people were mostly connected to folks they felt they could trust. But once you saw this growth of the internet and the worldwide web running on top of it in the 90s, then very quickly [they realized] no, you can’t just trust arbitrary computers you connect to.

But educational conservatism isn’t all bad. It’s actually sensible to teach things that have stood the test of time, which security has. The fundamental [computing] design principles have been known [about] since the 1970s.

RECOMMENDED ‘Security teams often fight against developers taking control’ of AppSec: Tanya Janca on the drive to DevSecOps adoption

DS: Might there be a commercial incentive at work that favours coding quickly over coding securely?

DAW: Maybe to some extent for the for-profits, but I think the bigger for-profit issue is that if you know how to do [secure development], you can probably earn double or triple in industry [compared to teaching]. You’re not gonna teach.

I teach, but that’s my side hustle. I enjoy teaching. George Mason University is 20 minutes from me and more connected to industry than some other universities.

DS: How do we persuade or incentivize education providers to embed security into coding courses?

DAW: I think this is a solvable problem – basically, society needs to scream more loudly.

The US spends a tremendous amount of money financing degrees, including computer science. If we’re gonna pay, maybe we could have some criteria?

DS: Could the impetus behind ‘shifting left’ or DevSecOps help persuade education providers to change emphasis?

DAW: I would like to think so, but I think it’s much more societal and industry pressure continuing over a period of time [that will make the difference].

Right now DevSecOps [is practised properly by] a minority, and we need to make sure that [secure development is practised] not just the majority, but is [a baseline] expectation [of all developers].

ddddDevelopers are not being taught general security principles – let alone how to apply them, says Wheeler

Years ago, I pushed really hard to get security added to a course on software engineering and after a lot of pressure and debate [the provider] finally added the word ‘security’ – no content, just that security might be important!

The ACM software engineering curriculum guidance at least does talk about knowing how to develop secure software, but lacks key specifics.

But I'm willing to believe that with continued emphasis we can get academia and many other organizations on board with making sure that software developers know the fundamentals.

DS: What fundamentals should newbie developers be taught?

DAW: What are the common problems? How do we prevent them in general? How do you design software so it’s less likely to be attacked? And what kind of tools can help developers to deal with that?

These general principles and the ability to apply them are important [skills] but lacking today.

Read more secure software development news

The first thing I did when I joined the Linux Foundation in 2020 as an employee was develop a course on developing secure software fundamentals. Thousands of people have now signed up.

George Mason University initially agreed to do my course every other semester, and very quickly, it's in every semester – it’s in demand.

But it’s an optional graduate course. We do need, in society, people who drill in deeper and [become experts], but we also need every developer to know the basics.

DS: How important is it that developers understand how to use security tools?

DAW: If you’re doing DevOps, you pretty much need a CI pipeline, and this is an obvious place to insert security tools. But if the developer doesn't know what they’re doing, they won’t know what the tool is telling them and what to do about it.

A fool with a tool is still a fool. They’re not stupid – it's just that no one has told them. Education and tooling go hand in hand.

The tools are going to miss things or report things that are not actually problems in context. Computer programs don’t – can’t – know the full context.

But as long as developers know which tools to use and how, then they can do [some] amazing things.

DS: Finally, anything to say on OpenSSF’s various initiatives aimed at bolstering software supply chain security?

DAW: Whether it’s industry, academia or governments, we’re all using open source software, so my first pitch would be: get involved with the OpenSSF. We would love to see more people involved.

I was deeply involved in the concise guides for developing secure software and evaluating open source software. And earlier, the OpenSSF published guides for open source projects and security researchers on [handling] coordinated [vulnerability] disclosure.

The Alpha-Omega Project has funded the Python Software Foundation and is funding Eclipse, Node... They’re announced a new partnership with Rust. They've released some tools for finding vulnerabilities – again, trying to shift left.

There’s also some funding for SBOM work, a tool for a Python library for SPDX [Software Package Data Exchange], and an [enterprise] end users working group kicking off.

Killexams : Programming languages: Java 19 arrives and here's what's new
Image: Shutterstock

Oracle has announced the availability of Java 19 and Oracle JDK 19 for developers, the latest versions of what is arguably the world's most popular programming language. 

JDK (Java Development Kit) 19 arrives about six months after Java 18 and exactly a year after Java 17 – the most accurate long-term support (LTS) release of Java.

With the release of Java 17, Oracle announced plans to move JDK LTS releases from every three years to every two years, meaning the next LTS release will be Java 21 in September 2023. 

The open-source version of JDK 19 OpenJDK 19 is also available from Oracle under the GNU General Public License, version 2, with the Classpath Exception.

Also: The most popular programming languages and where to learn them

Oracle now releases new versions of Java every six months in March and September with the aim of giving developers smaller but more frequent updates than its previous big-bang updates every few years. LTS releases remain supported for at least eight years. 

As noted by Sharat Chander, Oracle's director of Java SE product management, JDK 17 was the second LTS under the release cadence announced in 2018. With it, Oracle introduced "new and simpler license terms" that allowed companies to use it at "no cost for at least the next three years, allowing one full year of overlap with the next LTS release."  

Oracle explained at the time that JDK 17 and future JDK releases are provided under Oracle's No-Fee Terms and Conditions (NFTC) license, a free-to-use license for Java 17. The license lasts for a year after the next LTS release and then Java 17 moves under the Oracle Technology Network License

Java 17 was a big deal. A survey by Java dev tool maker Perforce earlier this year found that 37% of its users were still on Java 8, which was released in March 2014. A further 29% used Java 11, released in September 2018. Both are LTS releases. Some 37% of the Perforce's 876 Java users planned to move to Java 17 LTS.  

That's a rather small sample of Java developers worldwide. Oracle notes that tech analyst IDC estimates there are 10 million Java developers, representing about 75% of full-time developers. Java ranks in the top three most-popular languages across multiple indexes, along with JavaScript/TypeScript and Python.

There's Java the programming language and then there are several Java platforms that Java apps run in, consisting of the Java Virtual Machine or "JVM" and its application-programming interfaces. The two main platforms are Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE). 

Chander notes that "Java SE subscribers get access to Oracle's Java SE Support and commercial features such as GraalVM Enterprise, Java Management Service and the Advanced Management Console," pointing users to The New Java SE License Terms blog for details about the license. 

As for new technical features, Java 19 includes seven JDK enhancement proposals (JEP), but they're mostly preview or incubator features.

Notably, Java 19 includes JEP 422 - Linux/RISC-V Port, which ports the JDK to the open-source Linux RISC-V architecture. RISC-V has in various measures won the support of Intel via its new foundry services business and NASA, which wants to use RISC-V chips for its next-generation spaceflight computers.  

The RISC-V (pronounced "risk-five") standard was invented by University of California Berkeley professors David Patterson and Krste Asanović 12 years ago. Developers are free to change a RISC-V chip's instruction set architecture (ISA) versus the closed ISAs of Intel x86 and Arm processors.  

Another interesting addition is JEP 425 "Virtual Threads (Preview)" for the Java platform. Virtual Threads is the first JEP as part of Project Loom, a multi-year effort to Excellerate Java's performance on large server applications. 

"Virtual Threads are lightweight threads that dramaticaly reduce the effort of writing, maintaining, and observing high-throughput concurrent applications," note the proposal's authors.

Also: How to run websites as apps with ease in Linux

Chander explains the benefits of virtual threads versus Java's threads and how Project Loom aims to come up with an alternative to the three "bad options" developers have, which is to waste hardware through underutilization, waste programmer effort with worse programming models and observability, or switch away from Java.

"There are a lot of great things about Java's threads. They offer a natural programming model, with readable, sequential code using control flow operators that users understand – loops, conditionals, exceptions. Users get great debugging and serviceability, and readable stack traces. And threads are natural units of scheduling for OSes," Chander points out.

"The problem is that the implementation of threads by the OS is too heavyweight. It takes too long to start a thread for each connection, but worse, the number of threads the OS can support at any one time limits the number of concurrent transactions a server can handle – to well below the capacity of the hardware or the network – and so threads become a severe constraining factor on server throughput."

He said many people assumed Oracle would embrace the asynchronous programming style offered by so-called "reactive" frameworks but added: "Reactive may be the best people can do with the current JVM, but our goal is to do better, which we can do by making threads lighter and more scalable, letting developers keep using the model and tooling they've been using successfully for years."

Here's a list of all seven JEPs in Java 19:
