Parth Chandra updated CALCITE-612:
----------------------------------
Attachment: CALCITE-612.2.patch.diff
Updated patch. Looks like master already addressed the issue in
AvaticaResultSet. The patch now includes an update only for AvaticaStatement.
> Avatica framework throws NPE if ResultSet.getNext is called after the query
> is canceled

> Once the application cancels a query, the cursor corresponding to the result
> set is set back to null and any attempt to get the results results in a NPE.
> AvaticaStatement:internalExecute and AvaticaResultSet:next should check the
> state of the cursor and return false.
