>             Project: Geode
>          Issue Type: Bug
>          Components: functions
>    Affects Versions: 1.1.0
>            Reporter: Jason Huynh
>            Assignee: Jason Huynh
>
> If a function isHA and hasResult, if checkForBucketMovement() throws the 
> BucketMovedException, this escapes the synchronized lastResult() method.  
> Propogating this to through the user function.  
> Hopefully the user function does something appropriate or allows it to 
> propagate to AbstractExecution.executeFunctionLocally(), which hands it to 
> handleException.  Here is where the exception is written back to the client.
> However, because we have now escaped the synchronized method, the thread can 
> be paused.  
> A remote execution returns with results and now enters the synchronized 
> lastResult() method.  The state flags have been set and now this result is 
> considered the last result and lastResult is now sent.  We end up not 
> retrying even though the local node had failed.  It just hadn't had the 
> opportunity to send the exception back.
> This issue has probably been in the product for a long time.
