In JDK-8213307 we found that the code during the pause for cleaning up the ProtectionDomainTable and the ResolvedMethodTable only notifies the ServiceThread to do the actual cleanup, but does not do any actual cleanup.

Still the two notification calls contain timing code and show up in the logs as such. This timing information is useless as it does not time the actual work, but (the negligible) work to notify a mutex.

Move this timing code to represent the actual cleanup code execution.
