David Capwell commented on CASSANDRA-15981:
-------------------------------------------
might be ok to still define MaxMetaspaceSize, I tested disabling unloading in
CMS (it will unload, but only at stop-the-world pause) and removed
MaxMetaspaceSize. Without the change it failed frequently in my CI (I setup
the jobs to split the tests over 15 containers and ran 15 times), with the
change I never noticed a failure.

> Key: CASSANDRA-15981
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15981
> Project: Cassandra
> Issue Type: Bug
> Components: Build
> Reporter: David Capwell
> Priority: Normal
> Fix For: 4.0-beta
>
>
> There is a race condition bug with CMS and class unloading which cause the
> JVM to crash. Since jvm-dtests rely on class loaders and unloading, this
> causes sporadic JVM crashes that look like the following in CI logs
> {code}
> junit.framework.AssertionFailedError: Forked Java VM exited abnormally.
> Please note the time in the report does not reflect the time until the VM
> exit.
