I'm getting the following error when I attempt to run my Drools
application. I recently upgraded from Drools 5.0.1 and Guvnor 5.0.1 to
5.1.1 (for both). I've looked through the rules-users list and I found
the issue with the XML Change Set (authentication), which I've addressed
(XML listed at the bottom), but I'm still getting the error. Does
anyone have any ideas or can point me in a particular direction?
Thanks
