Java News Roundup: Liberica JDK Performance Edition, GraalVM JDK 21 Builds, Open Liberty, Quarkus
Aug 08, 2023 6 min read
This week's Java roundup for July 31st, 2023 features news from OpenJDK, JDK 22, JDK 21, GlassFish 7.0.7, GraalVM JDK 21 Developer Builds, Liberica JDK Performance Edition, JNoSQL 1.0.1, Spring Tools 4.19.1, Open Liberty 23.0.0.8-beta and 23.0.0.7, Micronaut 4.0.3, Quarkus 3.2.3 and 2.16.9, Apache Camel 4.0.0-RC2, JHipster Lite 0.40, Ktor 2.3.3, Maven 3.9.4 and Gradle 8.3-RC3.
OpenJDK
David Delabassee, director of Java developer relations at Oracle, has announced a change in annotation processing. The OpenJDK team is considering disabling default implicit annotation processing in a future release of OpenJDK. This is due to implicit annotation proceeding when there are no annotation processing configuration options. As of JDK 21 Build 29 and JDK 22 Build 4, the javac
utility will print a note (as shown below) if implicit annotation processing is being used.
Annotation processing is enabled because one or more processors were found on the class path. A future release of javac may disable annotation processing unless at least one processor is specified by name (-processor
), or a search path is specified (--processor-path
,--processor-module-path
), or annotation processing is enabled explicitly (-proc:only
,-proc:full
). Use-Xlint:-options
to suppress this message. Use-proc:none
to disable annotation processing.
JDK 21
Build 34 of the JDK 21 early-access builds was also made available this past week featuring updates from Build 33 that include fixes to various issues. Further details on this build may be found in the release notes.
JDK 22
