I'd like to propose that our Docker image for Solr 9 move from Java 11 to Java 17. Admittedly I don't have any familiarity with running 17, so I would really like to hear from those of you using it. I'm guessing (informed from some quick google searches) there are some ~minor performance improvements but nothing eye-popping there. Mostly, I propose this because a 9.0 release is an ideal time to make such a change instead of some minor release in between that could introduce a subtle surprise for some users. The new Shenandoah GC looks exciting but may not be sufficiently ready for us to recommend (if I recall from a recent user who reported a problem with it) -- and that's okay. Having this as an option for users is great, especially as time progresses and future Docker Solr releases include minor updates to the JVM base image that will increase the viability.
I'm aware our nifty image building enables people to do a custom build to specify their own preferred FROM image, which is cool. Still, I think we should move on to 17 as the default. ~ David Smiley Apache Lucene/Solr Search Developer http://www.linkedin.com/in/davidwsmiley
