This looks great. I got the ClassloaderLeakUnitTestCase.testSimpleWar passing by clearing the WebMetaData class loader refs the report showed. The associated root was a ThreadLocal entry that I currently don't see how could exist. Its cleared at the end of every request so either I'm missng somethng or there is another one in the thirdparty layer.
