Phil,

It helps to use jtreg 4.1 b02, and to use -agentvm instead of -samevm.  
Agentvm is like samevm, but better.  It tries to clean up after tests, 
and if it can't, it closes the JVM and starts a new one.

Also, in b03, upcoming, jtreg supports concurrent test execution, if the 
tests are up to the challenge.
