NPEs in AriesFrameworkUtil and DefaultWorker static initializers
----------------------------------------------------------------
Key: ARIES-776
URL: https://issues.apache.org/jira/browse/ARIES-776
Project: Aries
Issue Type: Bug
Components: Util
Affects Versions: 0.4
Environment: Using Pojosr 0.6
Reporter: Stan Lewis
Priority: Minor
Attachments: ARIES-776.txt
Working on getting some tests together using pojosr but the following exception
prevented some services from starting properly:
Running org.fusesource.fabric.service.FabricServiceImplTest

Avoiding the above NPE in AriesFrameworkUtil yielded a second NPE in
DefaultWorker's static initializer:

Avoiding this NPE allows me to get a valid service reference from the pojosr
registry for the service I want to test, so I'm attaching a patch for review,
would be good to avoid these NPEs in any case since it's not obvious what's
wrong when they occur.
