/**
|
|
* 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>
