[jira] [Created] (CALCITE-612) Avatica framework throws NPE if ResultSet.getNext is called after the query is canceled

Parth Chandra created CALCITE-612:
-------------------------------------

             Summary: Avatica framework throws NPE if ResultSet.getNext is called after the query is canceled
                 Key: CALCITE-612
                 URL: https://issues.apache.org/jira/browse/CALCITE-612
             Project: Calcite
          Issue Type: Bug
            Reporter: Parth Chandra
            Assignee: Julian Hyde


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.
