Description

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

junit.framework.AssertionFailedError: Forked Java VM exited abnormally. Please note the time in the report does not reflect the time until the VM exit.
