* If a VM could not create an RMI registry because the registry port
* was already occupied by this or other processes, the next
* time the VM tried to create a registry (after the other registry
* was brought down) the attempt would fail. The second try to create
* a registry would fail because the registry ObjID would still be in
* use when it should never have been allocated.
*
* The test creates this conflict starting a dummy tcp server and ensures
* that a registry can still be created after the conflict is resolved.
