Hi Apache Ozone community, Ozone currently requires minimum Java 8 at both build and run time, but it compiles and runs fine with newer Java versions. The GitHub CI workflow includes compilation with Java 11, 17 and 21. Tests are run with Java 17.
Java 21 has been GA for more than a year, Java 17 for 3 years now. [1] Some third-party dependencies have stopped releasing fixes for versions that work with Java 8. - Derby requires Java 21 [2] - Spring and jOOQ require Java 17 [3], [4] These are used only by Recon. To continue receiving fixes for these dependencies, we would need to bump the minimum Java required for building Ozone. We would also require the same version for running server components. Client components should still be usable with Java 8. I think the next major version, 2.0 would be a good candidate to make such a move. We should continue to support Java 8 with 1.4.x. What do you think? -Attila [1] https://www.oracle.com/java/technologies/java-se-support-roadmap.html [2] https://db.apache.org/derby/derby_downloads.html [3] https://docs.spring.io/spring-framework/reference/6.0/overview.html [4] https://www.jooq.org/download/versions#oss --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@ozone.apache.org For additional commands, e-mail: dev-h...@ozone.apache.org
