CLONE -Deadlock when logging trace
----------------------------------

                 Key: JBAS-4514
                 URL: http://jira.jboss.com/jira/browse/JBAS-4514
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: chris effenberger
         Assigned To: Scott M Stark


SourceForge Submitter: genman .


This was caused when trace was enabled.  I imagine it
was caused by the classloader trying to load a class
while it was being rendered (?) to disk.  Probably not
a big issue, unless trace-logging is enabled.
