NullPointerException during deployment of EJB3 methods with zero parameters

Deploying an EJB3 based EAR results in an NPE with the below stack trace. The problem appears to manifest with EJB3's containing methods that take zero arguments. There are also XML descriptor based attributes for several of the metadata elements. To the best of my knowledge the descriptors only augment, not override anything specified in annotations.

Patch for this should be trivial (an additional null check on line 83 of RolesAllowedProcessor.java should do it). I'm in the process of attempting to get JBMETA built from source and integrated into my stack. Will attach patch & tests unless someone beats me to it.

The stack:
