Unclear. Same stacktrace as PAXEXAM-699 , so what's the point?

If you refer to the exception thrown by org.apache.karaf.service.guard.impl.GuardProxyCatalog, please raise an issue with Karaf.

I haven't noticed this NPE in plain Karaf and it always shows up close to the one in PAXEXAM-699 - so they might be related :question:.
