PessDistCacheOperationsTest is failing randomly

I found that the ResetOfflineStatusTest is not closing all the JGroups channel after the test because it is using a DelegatingTransport. The delegatingTransport.stop() is never invoked because it is not present in the metadata extracted when the code is compiled (i.e. the GCR cannot find any stopMethods)

solution: I've created an abstract class in the core and extended in the test suite. the component metadata persister will persist the abstract class and register the start()/stop() methods.
