> In the method cmdExecute()
> if the local co-ordinator receives an FunctionException of type FunctionInvocationTargetException or QueryInvocationTargetException from the remote server, setException is called which sets the lastResultReceived flag. This flag prevents other results from other threads to be sent to the client, as the client may have moved on. 
> If there were any other function exception it will just send the exception but not set the flag.
