*
|

* <p>Current JVMs seem not to be robust against long-running finalize methods,

* This class mitigates the problem by asynchronously shifting the bodies of

|

* make use of this in their finalize methods are the proxies used in the
|

* intra-process JNI UNO bridge and the inter-process Java URP UNO bridge (where
|
||||
* in both cases finalizers lead to synchronous UNO release calls).</p>
|
||||
*
|
||||
* <p>Irrespective whether JVMs are getting more mature and should no longer
|
||||
* have problems with long-running finalize methods, at least the JNI UNO bridge
|
||||
* needs some way to stop finalization of proxies (to C++ objects) well before
|
||||
* process exit, as provided by drain().</p>
