Hi Arrow Java developers, I would like to propose a timeline for dropping support for Java 8: - Propose to drop JDK8 in Arrow v15 (2 releases from now) - JDK 21 support will be added before removal of JDK8
Why? - Java 8 no longer receives Premier Support (1) - Some Arrow Java (test) dependencies have already started to drop Java 8 support, forcing us to pin to older packager versions Also note: - gRPC Java may drop support for a JDK version when that version is no longer receiving Premier Support from Oracle (2), more detail at Java 8 / Java 11 support timeline in gRPC here (3) - Spark plans to tentatively drop JDK 8 support in Spark 4.0 (4), which has a release timeline of approximately 2024-06 (5). Is it fine for us to drop JDK 8 support before spark? (1) https://www.oracle.com/java/technologies/java-se-support-roadmap.html (2) https://github.com/grpc/proposal/pull/283/files#:~:text=gRPC%20Java%20may,support%5D. (3) https://groups.google.com/g/grpc-io/c/-XK6Kd_19YQ/m/-4s07TzdAgAJ (4) https://issues.apache.org/jira/browse/SPARK-44112 (5) https://www.mail-archive.com/dev@spark.apache.org/msg30460.html Consider: - JDK8 deprecation is currently not mandatory. We simply want to devote more time to development of Java LTS versions 11, 17 and 21. - Java 11 is dropping Premier Support this month. Best regards, -- David Susanibar
