Jan Høydahl updated SOLR-16463:
-------------------------------
Description:
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
Due to a known bug in current JDK 17 and later (see
[https://lists.apache.org/thread/wg7qtkddd1t5h08okj7gm9qbrpdf0ox6] and
[)|https://bugs.openjdk.org/browse/JDK-8285835)] due o Hotspot JIT
optimization o.
in e.g. a kubernetes environent.
A known workaround is to build your own Solr docker image on JRE11. Let's
provide a convenience official image on temurin11 for 9.0 users, and consider
it for the upcoming 9.1 release too if the issue is not resolved by then.

While this is due to a JDK bug
([https://bugs.openjdk.org/browse/JDK-8285835|https://bugs.openjdk.org/browse/JDK-8285835)])
it will likely not be fixed soon in JDK17(?), so we should make a workaround
