Null Pointer Exception in LibgcjInternalFinalizerThread

[Rudy Nedved <ern at spinnakernet dot com>]

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:
