Andrey Yakushev updated HARMONY-3377:
-------------------------------------

    Attachment: ClassObjectIDTest_cleanup.patch

For me the source of the problem is in presiding running test ClassObjectIDTest which sets jpda.settings.transportAddress property and doesn't cleaning it. ListenConnectorTest uses this property, but socket is still in TIME_WAIT mode and listening fails. 

ClassObjectIDTest_cleanup.patch provides cleanup of the property. ListenConnectorTest after that patch goes without the fail in a batch running.

Probably such cleanup should be added to several other tests. Another possibility is adding cleanup or setting the properties in the beginning of each test or waiting the socket availability.
