Thanks.

OK. We've seen this problem before (but not on a mac, at least not  
that I've seen...). IMO this is a JRE bug -- http://bugs.sun.com/ 
bugdatabase/view_bug.do?bug_id=5088398

We worked around the issue and seems to be working in other  
environments --  https://issues.apache.org/jira/browse/GERONIMO-3141

I've never seen this problem on my intel MacBook Pro -- a bit curious  
about  how you can reproduce so easily... Meantime will see how else  
we can work-around...
