    Description

      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):
      Database product: Apache Derby
      Database version: 10.3.1.5 - (579866)
      Driver name: Apache Derby Embedded JDBC Driver
      Driver version: 10.3.1.5 - (579866)
      result: 2

      Correct results:
      Database product: Apache Derby
      Database version: 10.2.2.0 - (485682)
      Driver name: Apache Derby Embedded JDBC Driver
