I have managed to test this situation out again, with current 5.5.14-beta, the
multiple ZIP failures are gone, handling looks much cleaner, but Tomcat's still
upset and every 10 seconds an NPE (the 2nd stack dump) occurs.
To re-create this situation I just did a rename of the application directory like:
mv $CATALINA_BASE/webapps/ROOT /tmp/ROOT
Please advise what I can do myself to help track down the persistant NPE problem
to help you fix it.
