25 * @bug 4513223
26 * @summary After an instance of UnicastRemoteObject has been unexported,
27 * if it gets marshalled, an InternalError should not be thrown; instead,
28 * the marshalling should succeed.  Also, if its "local" LiveRef gets
29 * marshalled, by way of the stub returned by RemoteObject.toStub, for
30 * example, then that should also succeed, instead of throwing an
31 * IOException (see fixes for bugids 4353388, 4017232).  This test
32 * handles the case where the impl's RemoteRef is a UnicastServerRef2.
