Virtual Threads “dramatically reduces the effort of writing, maintaining, and observing high-throughput concurrent applications by introducing lightweight virtual threads to the Java Platform. Meanwhile, perhaps the most significant feature in Java 19 is JEP 425, Virtual Threads, released in preview. Thus, we expect this trend to be going strong all the way till the next LTS release and maybe even later,” he said. “For instance, the addition of RISC-V port broadens the range of supported platforms, Foreign Function & Memory API enables the usage of data outside of the JVM, and virtual threads will make Java an ideal choice for high-throughput concurrent applications. BellSoft is a key OpenJDK contributor and provider of the Liberica JDK.Ĭhuyko noted that JEPs added to JDK19 demonstrate that Java strives to be a universal programming language used in any environment, for any task, and with any technology. It is right in the middle between LTS releases, which means we can already trace the trends of Java evolution,” said Dmitry Chuyko, Performance Architect at BellSoft, in a blog post. “There is one aspect that makes Java 19 remarkable. Oracle intends to make future LTS releases every two years. The last LTS release was Java 17 released in September 2021 and the next one will be Java 21, which is due in September of 2023. Java 19 comes smack dab in the middle of Long-Term-Support (LTS) releases of the platform. “Still, seeing the RISC-V port of the JDK (JEP 422) finding a home in the mainline codebase is great because it will open Java up to a new world of edge and IoT devices.”

“As this is the tenth iteration since Oracle moved to its rolling six-month updates, I think this cadence highlights the fact that Oracle and its global user community have settled into a very workable rhythm with new incubator, preview, and production code flowing smoothly from one release to the next,” Brad Shimmin, an analyst at Omdia, told The New Stack. Instead, now, what we’re finding is that we’re having constant innovation, and these projects are able to sort of look across and see what others are doing, and dovetail those and find places where the combination is richer than the sum of its parts.”Įnterprises have become accustomed to the Java release cadence, observers say. “So the old model basically amounted to every three years, kind of emptying the pipeline, and then you have to start over from scratch. “With this six-month cadence, you know, basically, our pipeline for innovation has become ongoing,” Saab said. Java 19 marks the tenth such release, which provides a steady stream of innovations. To maintain the rate of improvement to Java, five years ago Oracle instituted a six-month cadence for releases of the platform. Most of these updates are to be delivered as follow-up preview features improving on functionality introduced in earlier releases, said Georges Saab, senior vice president of development, Java Platform and Chair, OpenJDK Governing Board, Oracle. With the latest release of the platform, Java 19, also known as Java Development Kit (JDK) 19, Oracle has done just that - applying updates and improvements with seven JDK Enhancement Proposals (JEPs). Java is the workhorse of programming languages and Oracle continues to build upon both the language and development platform, providing enhancements not only to improve productivity, stability, performance and security, but also to lay a foundation for the future of the language.
