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...
