[wildfly-dev] Seeing NPE in org.jboss.as.weld.ejb.StatefulSessionObjectReferenceImpl.isRemoved() during NoSQL testing, how to fix?

[Scott Marlow]

Often when running a NoSQL unit test, I'm seeing a NPE in 
org.jboss.as.weld.ejb.StatefulSessionObjectReferenceImpl.isRemoved().  I 
understand that we should never allow a NullPointerException to be 
thrown, however, does anyone know what the correct course of action 
should be?  Ensuring that ejbComponent.getCache() never returns null 
could be one approach.  Or perhaps callers to ejbComponent.getCache() 
should check for null being returned.  Could there be a missing 
application dependency on the cache?

StatefulSessionObjectReferenceImpl currently contains:

@Override
public boolean isRemoved() {
   if (!removed) {
     return !ejbComponent.getCache().contains(id);
   }
   return true;
}

Thanks,
Scott
