| * @bug 4924577 |
| * @summary When the current RMIFailureHandler (if any) is invoked |
| * because of a server socket accept failure, if it returns false, |
| * then (in addition to the accept loop terminating) the associated |
| * server socket should be closed. The server socket should also be |
| * closed if the accept loop terminates because of an unexpected |
| * exception for which it doesn't even consult the RMIFailureHandler. |
