Steven Hawkins resolved TEIID-2331.
-----------------------------------

    Fix Version/s: 8.3
       Resolution: Done


It's correct that the client is not expecting results - otherwise a ResultsReceiver would be available.

The fix just refines the current checks to make it clear to exit if there is no receiver and to explicitly not consult the buffering logic in the continuous case.  This will need to be refined later if we do want to offer remote continuous or just want to allow useCallingThread = false such that results buffering is needed.
