Jan Høydahl commented on SOLR-16463:
------------------------------------
{quote}Of course, but it is not at all clear from all the commentary in this
issue and in the PR in `solr-docker` that there will actually be a fix for the
9.0 Dockerfile. Is that the actual plan?
{quote}
This Jira was repurposed for the 9.1 fix which is an actual solr-repo code
change.
The patch in 'solr-docker' for already-released 9.0 image seems to be warranted
to help the thousands of users who will be running 9.0.0 docker from now and
several weeks until they are ready to jump to 9.1. The workaround won't work
for everyone, but seems like consensus for pushing it.

> 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.
