Null Pointer Exception in LibgcjInternalFinalizerThread

Thu Mar 4 17:19:00 GMT 2004

Hi.
I am getting a null pointer exception in libgcj's finalizer thread using the
3.3.1 gcc and some additional deltas pulled in from 3.3.3.
The stack trace pops up after a while in a large java system and shows
 java.util.Vector.addAll(Collection c)
being called by the finalizer thread with probably a null pointer
for the collection....
I found a thread discussing something similiar but related to reference
objects:
 http://gcc.gnu.org/ml/java/2003-08/msg00247.html
My *real* question is why can't you have finalizations causing exceptions? 
Shouldn't this be expected and ignored?
Any insight would be helpful...
My apology for lack of fluency in Java....
Thanks,
-Rudy
P.S. The stack trace is as follows:
