/* @test

 * @bug 6332349

 * @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).
