Everything is running on the one EC2 instance. It's identical to the localhost deployment except being accessible over an Internet IP address.
One of the stack traces I'm getting (and this isn't all the time!!) when I do refresh on the 'Personal tasks' is:
-------------

If I do a refresh on the 'Group Tasks' I get this stack trace every time:

NOTE: I get this same dump on the localhost version as well, so this is clearly a bug in the JBPM-console.
It would be really useful if you guys have tested this on a production server and have some notes on how to deploy it (except on localhost)?
