This change is very interesting and looks fine to me for the record, but you didn't add the test.  I'm a bit greedy for class loading and unloading tests.  Even if it has timing dependencies to show the bug, I think it would be worth adding to jtreg.  Could you add it with a follow-on RFE?  Thanks!
