| * @bug 4322806 |
| * @summary When an RMI (JRMP) connection is made to a TCP address that is |
| * listening, so the connection is accepted, but the server never responds |
| * to the initial JRMP handshake (nor does it terminate the connection), |
| * the client should not hang forever; instead, it should throw an exception |
| * after a reasonable timeout interval. The exception should be a |
| * java.rmi.ConnectException or ConnectIOException, not a MarshalException, |
| * because it should be clear that no partial call execution has occurred at |
| * this point (because no data for the invocation has yet been written). |
