* @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
