Quick update:

We're still trying to integrate PicketLink 2.7 with WildFly 8.2.0.

I will provide an additional examples and logs of what's not working, but the bottom line is as follows:

• The only place where PicketLink works as a module dependency with jboss-deployment-structure.xml seems to be a standalone WAR.
• When said WAR is inside an EAR, you HAVE to include PicketLink JARs in the WEB-INF/libs of every WAR or things simply don't work (various failures or silent failures)
