26 * @summary Whan an RMI (JRMP) connection is made to a TCP address that is
27 * listening, so the connection is accepted, but the server responds with
28 * invalid JRMP protocol (such as because a non-JRMP server is currently
29 * listening at that address), the client application should receive a
30 * java.rmi.ConnectException or ConnectIOException, not a MarshalException.
