/**
* Test case for bug #110892#.
*
* <p>Bug #110892# "Java URP bridge holds objects indefinitely" applies to cases
* where an object is sent from server to client, then recursively back from
* client to server. In such a case, the client should not increment its
* internal reference count for the object, as the server will never send back a
* corresponding release message.</p>
*
* <p>This test has to detect whether the spawned client process fails to
* garbage-collect an object, which can not be done reliably. As an
* approximation, it waits for 10 sec and considers the process failing if it
* has not garbage-collected the object by then.</p>
