Re: deadlocks

hi mark-

i'm not able to line up your stack trace line numbers with mine,
probably because i'm using a different JConsole, so i can't tell
exactly what's going on. but, i did some work on threading issues
with JConsole in the past. they haven't been merged into CVS yet,
so i attached my version of JConsole (zipped to get in under
sourceforge size limit). i'm not sure if i addressed the issue you're
having, but it might be worth a try. my version of JConsole has been
used by a large number of people for several months on several
different platforms without issue; although i know there is *always*
one more bug :)
