Rob Harrington commented on HHH-951:
------------------------------------

I am seeing this in 3.2.5.ga.  I am working on porting from 3.0.5, for which this was not an issue.  For me, it's not a case sensitivity issue, or not qualifying the column with a table name or alias.  Using the Criteria API, something like this:

Criteria crit = buildQuery(opt); // huge method left out for brevity
crit.setFirstResult(0);
crit.setMaxResults(25);
c = crit.list();

results in something like this for SQL:

SELECT *
  FROM (SELECT   this_.io_item_a_id AS io1_14_5_,
                 this_.creation_dt AS creation2_14_5_,
                                  .
                                  .
                                  .
                 this_.package_main_fl AS package15_14_5_,
                 this_.insertion_order_id AS insertion16_14_5_, --dupe
                 this_.solomon_item_id AS solomon17_14_5_,
                 this_.parent_io_item_a_id AS parent18_14_5_,
                 this_.line_group_id AS line19_14_5_,
                 this_.io_item_state_cd AS io20_14_5_,
                 this_.insertion_order_id AS insertion16_14_5_, --dupe
                 this_.assignment_id AS assignment21_14_5_,
                                .
                                .
                                .
                 packageins9_.package_instance_id AS package1_84_4_,
                 packageins9_.bundle_cd AS bundle2_84_4_
            FROM [removed for brevity]
           WHERE [removed for brevity]
        ORDER BY [removed for brevity]
             )
 WHERE ROWNUM <= 25

So as you can see 'this_.insertion_order_id' is included twice with the same alias.  Obviously I've left out a LOT of detail and no Test Case.  Not including that for now in the hope that I've described the issue well enough to get feedback on whether this is a known issue or indeed requires more description (test case) from me, which will take a while to put together.
