| * @library ../../testlibrary |
| * @modules java.rmi/sun.rmi.registry |
| * java.rmi/sun.rmi.server |
| * java.rmi/sun.rmi.transport |

| /* |
| * 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. |
