>
> 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.
