| * @summary RMI needs a mechanism to dynamically change a VMs RMI |
| * serverHostname. If the java.rmi.server.hostname property is |
| * changed dynamically, newly exported objects should be exported |
| * with the new hostname instead of the value of the |
| * java.rmi.server.hostname property when the first object was exported. |
