SQL query with HAVING SubSelect gives NullPointerException

[at88mph]

The stack trace is below. The sample query is:

SELECT DISTINCT 
TABLE1.COL1A AS "COL1A",
TABLE1.COL1B AS "COL1B",
TABLE2.COL2A AS "COL2A",
TABLE3.COL3A AS "COL3A"
FROM SCHEMA1.TABLE1
inner join SCHEMA1.TABLE2 on TABLE1.COL1A = TABLE2.COL2A
inner join SCHEMA1.TABLE3 on TABLE2.COL2B = TABLE3.COL3A
WHERE (1=1)
AND TABLE3.COL3A = 'VAL'
GROUP BY TABLE1.COL1A, TABLE1.COL1B, TABLE2.COL2A, TABLE3.COL3A
HAVING TABLE2.COL2A = 
  (SELECT MAX(T3.COL3A) AS MM FROM TABLE3 AS T3
   inner join TABLE1 as t1 on t1.COL1A = T3.COL3A
   inner join TABLE2 as t2 on t2.COL2B = t1.COL1B
   WHERE t1.COL1A = TABLE1.COL1A)
ORDER BY "COL1A" asc;

I have confirmed that upgrading the jSQL parser fixes this issue.

Depends on #3 .
