+/**
+ * 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>
