This week’s Java roundup for August 29th, 2022, features news from OpenJDK, JDK 20, Eclipse GlassFish 7.0.0-M8, Quarkus 2.12.0, Open Liberty 22.0.0.9 and 22.0.0.10-beta, MicroStream 07.01.00-beta2, WildFly 26.1.2, JHipster 7.9.3, EclipseLink 4.0.0-RC1, Hibernate 5.6.11, JDKMon 17.0.35 and Apache Camel Quarkus 2.12.0.

OpenJDK

Joe Darcy, member of the technical staff at Oracle, Java Platform Group, has proposed to drop support for -source/-target/--release 7 command-line options from javac with the release of JDK 20. Darcy refers to JEP 182, Policy for Retiring javac -source and -target Options, that discusses the appropriate time frame to support older versions of the JDK. Feedback, so far, has been a concern for the Maven compiler plugin that still uses version 1.7 as default.

Magnus Ihse Bursie, principal member of technical staff at Oracle, has proposed to drop support for Visual Studio 2017 (VS2017) for the following reasons:

• VS2017 was moved to “Mainstream End Date” by Microsoft in April, 2022
• VS2017 does not support C11 properly, which makes the fix for JDK-8292008 non-ideal
• VS2017 does not support the new conformant preprocessor, which will likewise make JDK-8247283 only half-fixed
• VS2017 required ugly workarounds like, JDK-8286459, which should likely be reverted once support has been dropped

Feedback, so far, has been a concern for development teams that still use VS2017.

JDK 19

JDK 19 remains in its release candidate phase with the anticipated GA release on September 20, 2022. The release notes include links to documents such as the complete API specification and an annotated API specification comparing the differences between JDK 18 (Build 36) and JDK 19 (Build 36). InfoQ will follow-up with a more detailed news story.

JDK 20

Build 13 of the JDK 20 early-access builds was also made available this past week, featuring updates from Build 12 that include fixes to various issues. Further details on this build may be found in the release notes.

For JDK 19 and JDK 20, developers are encouraged to report bugs via the Java Bug Database.
