Dominik Stadler commented on XMLBEANS-616:
------------------------------------------

Are you sure this is a deadlock? A RUNNABLE thread is not blocked by any lock, 
it is rather currently doing work or could do work if CPU would be available, 
so this does not indicate a deadlock.

Can you attach a full thread-dump with all threads so we can take a look? E.g. 
via "jstack <id of the process>".
