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