NullPointerException during deployment of EJB3 methods with zero parameters
---------------------------------------------------------------------------

                 Key: JBMETA-207
                 URL: https://jira.jboss.org/jira/browse/JBMETA-207
             Project: JBoss Metadata
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 1.0.0.GA
         Environment: JBoss-5.1.0-GA, JDK 1.6.0_07-b06-153 (Apple/Sun JVM, 64-bit on OS/X), EJB3 w/ descriptor overrides
            Reporter: Zachary Bedell
            Assignee: Alexey Loubyansky


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:
