David Capwell commented on CASSANDRA-15981:
-------------------------------------------
testing out a change that defines max meatspace only in java 8 and
-CMSClassUnloadingEnabled on java 11. I am testing by running jvm-dtests and
upgrade jvm-dtests with 4gb containers repeatedly; this method helps show there
is a problem, so should show that it is resolved.
> jvm-dtests crash on java 11

> URL: https://issues.apache.org/jira/browse/CASSANDRA-15981
> Project: Cassandra
> Issue Type: Bug
> Components: Build
> Reporter: David Capwell
> Assignee: 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.
