hang loading plugin during validation

I was doing a 'RunAnt' on a build.xml that usually works, hung
partway through (validation of server project).

1) ctrl-break stack/trhead dump attached (mostly)
2) coredump also created (email searle@ca.ibm.com to get it)

1) crtl-break stack/thread dump:

threads):

javacore dump from hang
Comment 2 John Arthorne CLA 2002-05-20 10:57:15 EDT 
What a mess!

There seem to be four "active" threads, two are classloading, and two are doing 
other things.  It is not clear that this is "our fault".  Classloading always 
happens in a critical region, so it will always have some lock acquired during 
this process.  I don't know what has caused the other two threads to be blocked. 
 Why are there so many threads trying to work at once?  The deadlock could be 
caused by that DTD tooling code, since three of the threads are running code in 
"com.ibm.etools.dtd.".  I suggest that someone who is familiar with that 
(WSAD?) code  should take a look at those stack traces and figure out what is 
happening.
Comment 3 DJ Houghton CLA 2002-09-27 09:55:09 EDT 
This is being investigated by WSAD.
Please re-open if you determine this is a Platform problem.
Comment 4 Barry Searle CLA 2006-11-06 11:24:26 EST 
old bug.  closing.
