| * 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> |
