This week's Java roundup for October 24th, 2022, features news from OpenJDK, JDK 20 release schedule, Build 20-loom+20-34, Spring Integration 6.0-RC1, Spring Tools 4.16.1, GraalVM 22.3, Open Liberty 22.0.0.11 and 22.0.0.12-beta, Eclipse Vert.x 3.9.14, Apache TomEE 8.0.13, JReleaser 1.3.0, Hibernate Search 5.11.11 and 5.10.13, PrimeFaces point releases, JDKMon 17.0.37 and EclipseCon 2022.

OpenJDK

JEP 434, Foreign Function & Memory API (Second Preview), was promoted from its Draft 8293649 to Candidate status this past week. This JEP, under the auspices of Project Panama, evolves: JEP 424, Foreign Function & Memory API (Preview), delivered in JDK 19; JEP 419, Foreign Function & Memory API (Second Incubator), delivered in JDK 18; and JEP 412, Foreign Function & Memory API (Incubator), delivered in JDK 17. It proposes to incorporate refinements based on feedback and to provide a second preview in JDK 20. Updates include: the MemorySegment and MemoryAddress interfaces are now unified, i.e., memory addresses are modeled by zero-length memory segments; and the sealed MemoryLayout interface has been enhanced to facilitate usage with JEP 427, Pattern Matching for switch (Third Preview).

JEP Draft 8295817, Virtual Threads (Second Preview), has been promoted to Submitted status this past week. This JEP, also under the auspices of Project Loom, proposes a second preview from JEP 425, Virtual Threads (Preview), delivered in JDK 19, to allow time for additional feedback and experience for this feature to progress. It is important to note that no changes are within this preview except for a small number of APIs from JEP 425 that were made permanent in JDK 19 and, therefore, not proposed in this second preview.

Similarly, JEP Draft 8296037, Structured Concurrency (Second Incubator), has been promoted to Submitted status. This JEP, also under the auspices of Project Loom, proposes to reincubate this feature from JEP 428, Structured Concurrency (Incubator), delivered in JDK 19, in JDK 20 to allow time for additional feedback and experience. The only change is an updated StructuredTaskScope class to support the inheritance of scoped values by threads created in a task scope. This streamlines the sharing of immutable data across threads.

JDK 20

Build 21 of the JDK 20 early-access builds was also made available this past week, featuring updates from Build 20 that include fixes to various issues. Further details on this build may be found in the release notes.

Mark Reinhold, chief architect, Java Platform Group at Oracle, formally announced the release schedule for JDK 20 as follows:

  • Rampdown Phase One (fork from main line): December 8, 2022
  • Rampdown Phase Two: January 19, 2023
  • Initial Release Candidate: February 9, 2023
  • Final Release Candidate: February 23, 2023
  • General Availability: March 21, 2023

For JDK 20, developers are encouraged to report bugs via the Java Bug Database.
