UIMA AS service serializes Exception object which may contain user defined Exception class
not available to the client
----------------------------------------------------------------------------------------------------------------------

                 Key: UIMA-2304
                 URL: https://issues.apache.org/jira/browse/UIMA-2304
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.4.0SDK


When AE throws an exception UIMA wraps it in AnalysisEngineProcessException which is handed
off to UIMA AS. This exception is subsequently serialized as a java object and sent in a reply
to the client. The client deserializes the cargo back to a java Exception and hands it off
to the application via a callback. The problem is that the Exception stack trace may include
user defined Exception class(es) which are not available to the client thus causing ClassNotFound
while deserializing a reply. Modify UIMA AS service side to serialize an exception to a String
and send that to the client.
