> 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.
