CustomResourceFactory_impl not catching exceptions when calling out to initialize method
----------------------------------------------------------------------------------------

                 Key: UIMA-664
                 URL: https://issues.apache.org/jira/browse/UIMA-664
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
            Reporter: Marshall Schor
            Assignee: Marshall Schor
            Priority: Minor
             Fix For: 2.2.1


While testing the CDE, found an instance where a custom resource was incorrectly configured
(things were missing that it needed in the class path).  The result of this was a silent failure
to start the CDE editor, although an entry was noted in the Eclipse error log.  This was because
the missing class path caused a NoClassDefFound exception to be thrown, but nobody (except
the top-most Eclipse UI code) caught it.

I think the right place for putting a try/catch is around the point in the CustomResourceFactory
where it calls out to that resource's "initialize" method.  If that throws an exception, it
should be caught and wrapped with a new ResourceInitializationException, which says that the
nested exception happened while trying to initialize the custom resource, and identifying
the custom resource.
