There's no deadlock in your thread dump. There's just one thread holding a lock
and many other threads queing up behind. The thread that holds the lock is

As you can see the thread handles an exception. Stack creation for an exception
can be quite slow, especially if it happens very often. Bugzilla is not a
support forum. Please followup with your problem on the Tomcat users list.
