JDK-8300926 - Several startup regressions ~6-70% in 21-b6 all platforms
Description
The following two tests timed out with slowdebug bits with
stress testing:

vmTestbase/nsk/monitoring/stress/thread/cmon002/TestDescription.java
vmTestbase/nsk/monitoring/stress/thread/cmon003/TestDescription.java

Here's my tracking entries:

8209849 is closed bug associated with a Solaris timeout sighting from a long time ago.
I'll be updating the entry to this bug ID.
Comments
With the fix for the following bug in place: JDK-8300926 Several startup regressions ~6-70% in 21-b6 all platforms these two tests no longer timeout: vmTestbase/nsk/monitoring/stress/thread/cmon002/TestDescription.java vmTestbase/nsk/monitoring/stress/thread/cmon003/TestDescription.java so I'm closing this bug as "Cannot Reproduce".
