 * @summary Passing live remote references as part of the arguments of
 * a remote invocation should not cause an AssertionError (on the
 * second and subsequent attempts) when system assertions are enabled,
 * nor should it cause the references to be pinned until a subsequent
 * such remote invocation occurs (if the argument stream was not
 * released cleanly because of a marshalling failure).
