 * @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.
