OpenJDK

JEP 483, Ahead-of-Time Class Loading & Linking, has been promoted from its JEP Draft 8315737 to Candidate status. This JEP proposes to “improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts.” This may be achieved by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. This feature will lay a foundation for future improvements to both startup and warmup time.

JDK 23

Build 36 of the JDK 23 early-access builds was made available this past week featuring updates from Build 35 that include fixes for various issues. Further details on this release may be found in the release notes, and details on the new JDK 23 features may be found in this InfoQ news story.

As per the JDK 23 release schedule, Mark Reinhold, Chief Architect, Java Platform Group at Oracle, formally declared that JDK 23 has entered its first release candidate as there are no unresolved P1 bugs in Build 36. The anticipated GA release is scheduled for September 17, 2024. The final set of 12 features for the GA release in September 2024 will include:

More details on all of these new features may be found in this InfoQ news story.

JDK 24

Build 10 of the JDK 24 early-access builds was also made available this past week featuring updates from Build 9 that include fixes for various issues. Further details on this release may be found in the release notes.

Further details on this release may be found in the changelog.

Open Liberty

IBM has released version 24.0.0.8-beta of Open Liberty that introduces versionless features to simplify and streamline choosing compatible features for the MicroProfile, Jakarta EE and Java EE platforms.

This week’s Java roundup for May 27th, 2024 features news highlighting: four JEPs targeted for JDK 23, namely: JEP 482, Flexible Constructor Bodies (Second Preview), JEP 481, Scoped Values (Third Preview), JEP 480, Structured Concurrency (Third Preview) and JEP 471, Deprecate the Memory-Access Methods in Unsafe for Removal; and the releases of JHipster 8.5, Gradle 8.8 and Spring AI 1.0-M1.

OpenJDK

After its review has concluded, JEP 482, Flexible Constructor Bodies (Second Preview), has been promoted from Proposed to Target to Targeted for JDK 23. This JEP proposes a second round of preview and a name change to obtain feedback from the previous round of preview, namely JEP 447, Statements before super(…) (Preview), delivered in JDK 22. This feature allows statements that do not reference an instance being created to appear before the this() or super() calls in a constructor; and preserve existing safety and initialization guarantees for constructors. Changes in this JEP include: a treatment of local classes; and a relaxation of the restriction that fields can not be accessed before an explicit constructor invocation to a requirement that fields can not be read before an explicit constructor invocation. Gavin Bierman, Consulting Member of Technical Staff at Oracle, has provided an initial specification of this JEP for the Java community to review and provide feedback.

After its review has concluded, JEP 481, Scoped Values (Third Preview), has been promoted from Proposed to Target to Targeted for JDK 23. Formerly known as Extent-Local Variables (Incubator), this JEP proposes a third preview, with one change, in order to gain additional experience and feedback from one round of incubation and two rounds of preview, namely: JEP 464, Scoped Values (Second Preview), delivered in JDK 22; JEP 446, Scoped Values (Preview), delivered in JDK 21; and JEP 429, Scoped Values (Incubator), delivered in JDK 20. This feature enables sharing of immutable data within and across threads. This is preferred to thread-local variables, especially when using large numbers of virtual threads. The change in this feature is related to the operation parameter of the callWhere() method, defined in the ScopedValue class, is now a functional interface which allows the Java compiler to infer whether a checked exception might be thrown. With this change, the getWhere() method is no longer needed and has been removed.

After its review has concluded, JEP 480, Structured Concurrency (Third Preview), has been promoted from Proposed to Target to Targeted for JDK 23. This JEP proposes a third preview, without change, in order to gain more feedback from the previous two rounds of preview, namely: JEP 462, Structured Concurrency (Second Preview), delivered in JDK 22; and JEP 453, Structured Concurrency (Preview), delivered in JDK 21. This feature simplifies concurrent programming by introducing structured concurrency to “treat groups of related tasks running in different threads as a single unit of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability.”

After its review has concluded, JEP 471, Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal, has been promoted from Proposed to Target to Targeted for JDK 23. This JEP proposes to deprecate the memory access methods in the Unsafe class for removal in a future release. These unsupported methods have been superseded by standard APIs, namely; JEP 193, Variable Handles, delivered in JDK 9; and JEP 454, Foreign Function & Memory API, delivered in JDK 22.

Build 23-loom+4-102 of the Project Loom early-access builds are based on JDK 23 Build 25 and improves the implementation of Java monitors (synchronized methods) to work better with virtual threads.

Build 22-jextract+5-33 of the Project Jextract early-access builds, also known as Project Panama, are based on JDK 22 and provides a recommendation in which the quarantine attribute from the bits may need to be removed before using the jextract binaries on macOS Catalina or later.

JDK 23

Build 25 of the JDK 23 early-access builds was made available this past week featuring updates from Build 24 that include fixes for various issues. Further details on this release may be found in the release notes.

Jakarta EE

In his weekly Hashtag Jakarta EE blog, Ivar Grimstad, Jakarta EE Developer Advocate at the Eclipse Foundation, has provided an additional update on the upcoming GA release of Jakarta EE 11.

This week’s Java roundup for May 20th, 2024 features news highlighting: Java’s 29th birthday; the release of Kotlin 2.0 and Semantic Kernel for Java 1.0; JEP 477, Implicitly Declared Classes and Instance Main Methods (Third Preview), targeted for JDK 23; and four JEPs proposed to target for JDK 23

Java Turns 29

On May 23rd, 1995, Java 1.0 was introduced to developers who attended the Sun World ‘95 conference. A Java community was born and 29 years later, the community has evolved to include 370 global Java User Groups, 370 Java Champions and many Java-related conferences in a given calendar year. There have been 22 formal releases

At Devnexus 2024, Sharat Chander, Senior Director, Product Management & Developer Engagement at Oracle, announced that JavaOne will return to celebrate Java’s 30th birthday. It will be held March 17-20, 2025 in Redwood Shores, California. Please stay tuned for the call for papers.

OpenJDK

After its review has concluded, JEP 477, Implicitly Declared Classes and Instance Main Methods (Third Preview), has been promoted from Proposed to Target to Targeted for JDK 23.
