Ajay, if you can do more testing of your queries with this change applied, that would be helpful--and thanks for your patience in the meantime. Otherwise, assuming all goes well with tinderbox runs for the next few days, I'll plan to port the changes to 10.3 sometime late next week...

> Running the following produces the error seen in Derby 10.3.X but not in 10.2.X nor in 10.1.X.
> Don't know if this related to DERBY-3231.
> First query is incorrectly sorted whereas the second one is okay when there is an index on the table.
> If the table is not indexed, the sort works correctly in DESC order.
> ------
> create table CHEESE (
> CHEESE_CODE VARCHAR(5),
> CHEESE_NAME VARCHAR(20),
> CHEESE_COST DECIMAL(7,4)
> );
> create index cheese_index on CHEESE (CHEESE_CODE DESC, CHEESE_NAME DESC, CHEESE_COST DESC);
> INSERT INTO CHEESE (
