P.S. Your test is the fifth jtreg test to use the hack of grabbing the private field Unsafe.theUnsafe.  If there is an alternative to that, we should use it.  In particular, if jtreg allows test classes to be loaded on the boot class path, then the public method Unsafe.getUnsafe can be used, and that would be much cleaner.
