Steven Hawkins resolved TEIID-2225.

    Resolution: Done

Resolved with the commit to TEIID-2224.  An AsynchPositioningException will be thrown if a blocking method is called to change the position to results that have yet to be formed.

> I am executing a query using submitExecute(StatementCallback) under non-continuous mode.  In the onRow() method of the callback, I execute ResultSet.isLast().  The query is against an execution whose next() method initially throws DataNotAvailable.NO_POLLING.  Some time later, it calls ExecutionContext.dataAvailable().  After 255 rows reported through the callback's onRow(), ResultSet.isLast() hangs.
> I know that the entire result set is ultimately returned from the execution's next() and it returns null at the last call.
> See https://community.jboss.org/thread/205559?tstart=0 for more detail
