Whoops good catch, I'll fix that one

> Key: GEODE-2870
> URL: https://issues.apache.org/jira/browse/GEODE-2870
> 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.
