This week’s Java roundup for October 7th, 2024, features news highlighting: JEP 489, Vector API (Ninth Incubator), and JEP 484, Class-File API, targeted for JDK 24; the release of Apache projects, Tomcat 11.0.0 and Cassandra 5.0.0; the release of EclipseStore 2.0.0; the October 2024 Payara Platform release; and the release of Ktor 3.0.0.

OpenJDK

After its review had concluded, JEP 489, Vector API (Ninth Incubator), has been promoted from Proposed to Target to Targeted for JDK 24. This JEP incorporates enhancements in response to feedback from the previous eight rounds of incubation, namely: JEP 469, Vector API (Eighth Incubator), delivered in JDK 23; JEP 460, Vector API (Seventh Incubator), delivered in JDK 22; JEP 448, Vector API (Sixth Incubator), delivered in JDK 21; JEP 438, Vector API (Fifth Incubator), delivered in JDK 20; JEP 426, Vector API (Fourth Incubator), delivered in JDK 19; JEP 417, Vector API (Third Incubator), delivered in JDK 18; JEP 414, Vector API (Second Incubator), delivered in JDK 17; and JEP 338, Vector API (Incubator), delivered as an incubator module in JDK 16. Originally slated to be a re-incubation by reusing the original Incubator status, it was decided to keep enumerating. The Vector API will continue to incubate until the necessary features of Project Valhalla become available as preview features. At that time, the Vector API team will adapt the Vector API and its implementation to use them, and will promote the Vector API from Incubation to Preview.

After its review had concluded, JEP 484, Class-File API, has been promoted from Proposed to Target to Targeted for JDK 24. This JEP proposes to finalize this feature in JDK 24 after two rounds of preview, namely: JEP 466, Class-File API (Second Preview), delivered in JDK 23; and JEP 457, Class-File API (Preview), delivered in JDK 22. This feature provides an API for parsing, generating, and transforming Java class files. This will initially serve as an internal replacement for ASM, the Java bytecode manipulation and analysis framework, in the JDK with plans to have it opened as a public API. Goetz has characterized ASM as “an old codebase with plenty of legacy baggage” and provided background information on how this feature will evolve and ultimately replace ASM.

JEP 490, ZGC: Remove the Non-Generational Mode, was promoted from its JEP Draft 8335850 to Candidate status. This JEP proposes to remove the non-generational mode of the Z Garbage Collector (ZGC). The generational mode is now the default as per JEP 474, ZGC: Generational Mode by Default, delivered in JDK 23. By removing the non-generational mode of ZGC, it eliminates the need to maintain two modes and improves development time of new features for the generational mode.

JDK 24

Build 19 of the JDK 24 early-access builds was made available this past week featuring updates from Build 18 that include fixes for various issues. Further details on this release may be found in the release notes.
