Cassandra Targett commented on SOLR-16463:
------------------------------------------
I understand the workaround is simpler in a lot of ways, but it's for 9.1 so
anyone currently deploying or who wants to deploy 9.0 from a Docker image will
still have to customize their Dockerfile to get around it (or come up with some
other process that operates on every deploy).
Until we are sure the bug is fixed, why wouldn't we just use JDK 11 as the base
image instead of hoping we don't find anything else?

> Solr 9+ under JDK 17+ may crash frequently, during JVM Hotspot optimization
> of caffeine cache class.
> This is due to a JDK bug
> ([https://bugs.openjdk.org/browse/JDK-8285835|https://bugs.openjdk.org/browse/JDK-8285835)]),
> but may not be fixed soon in JDK17, so we should make a workaround to
> protect our users. The bug is also reported in caffeine project
> ([https://github.com/ben-manes/caffeine/issues/797]).
> So there are a few possible ways to avoid this
> * Run Solr 9 on JDK 11
> * Do not use caffeine cache, find some replacement
> * Caffeine cache releases a new version that do not suffer the issue, and
> solr uses that
> * Instruct JDK to not optimize that class, using JDK option
> {{-XX:CompileCommand=exclude,com.github.benmanes.caffeine.cache.BoundedLocalCache::put}}
> See users list for examples of this issue seen in the wild:
> [https://lists.apache.org/thread/wg7qtkddd1t5h08okj7gm9qbrpdf0ox6]
> Docker users can set SOLR_OPTS with the JDK option above. Patching the
> official Dockerfile to include this may be the least intrusive fix
> short-term. We should also document the issue on website and perhaps docker
> hub to provide users with a workaround.
> For 9.1 we can hardcode the JDK flag in bin/solr.
