Unfortunately, this is a known issue that remains open: https://bugzilla.redhat.com/show_bug.cgi?id=733008
What I don't understand is why Drools is trying to use a ReaderResource instead of a URLResource. Let me check into the source code to see what I find.

Yay, at long last a Java Stack Trace :)

This is a known problem, but one I believe has been fixed for 5.4.0.beta1 - correct me if I am wrong esteban.
