Knut Anders Hatlen updated DERBY-948:
-------------------------------------

    Attachment: DERBY-948-v3.diff
                DERBY-948-v3.stat

I investigated the possibility for null pointer exceptions
further. The only result sets that return null in getStatement() are
those created by getNewRowSet() and getOldRowSet() in
InternalTriggerExecutionContext. Those result sets are not exposed to
JDBC applications, so applications can't call getHoldability() on them
anyway. However, I updated the patch with a comment about the null
case, and made getHoldability() return CLOSE_CURSORS_AT_COMMIT instead
of throwing NullPointerException.
