             Summary: UIMA-AS: MessageTimeException not available to client on 
init failure
                 Key: UIMA-5784
                 URL: https://issues.apache.org/jira/browse/UIMA-5784
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.10.4AS


When an aggregate times out waiting for delegate GetMeta response, it does not 
include MessageTimeoutException as cause in an exception going back to the 
deployer. Instead is just provides ResourceInitializationException with no real 
cause. Some clients may need to know this in order to decide whether or not to 
retry uima-as initialization. 

In a specific case, a client deploys an aggregate with one of its delegates not 
yet available. 

Also fix service log message as it says: 

org.apache.uima.aae.error.MessageTimeoutException: Delegate Service:NoOp Has 
Timed Out While Processing CAS:null

In this case, the timeout was related to GetMeta. The message should clearly 
state what operation has timed out.
