When I run the attached test case with revision 603368, I get incorrect results, ie only one
count is returned back.

> Attached program demonstrates the problem.  Only one count is returned (matching CODE=
GBR) - the count of CODE=CHA is not returned.  Works fine with versions 10.1 and 10.2 or if
program is run using 10.3 jars and 10.2 database (soft upgrade).
> Query:
> SELECT COUNT(t0.ID) FROM CTS1.TEST_TABLE t0 
>   GROUP BY t0.CODE 
>     HAVING (t0.CODE = 'GBR' OR t0.CODE = 'CHA') AND t0.CODE IS NOT NULL
> Incorrect results (see last line):
