My question was about the symptoms - how the test can fail. If the test 
ignores NSME & VME exceptions, will it always pass w.r.t. code cache 
overflows?

Code cache overflow is definitely a JVM problem, but we don't plan to 
address it in the near future.

So, either the test should be excluded or adjusted to be tolerant to 
code cache overflows.

Vladimir Ivanov
