Join subquery containing ifnull in join condition

I have join subquery linked to main query via 2 fields in the query below.
To be able to join null values between main query and subquery, I have added ifnull to join fields with a random value.
If I run my query directly over mysql, the field CalculatedField1 return values whenever the field RESOLUTIONDATE is null in the main query.
But when executed in Teiid, the query returns always null for the field CalculatedField1.
When looking at the jdbc queries executed by Teiid, I found that ifnull is used for the main query fields but not for the subquery fields, which may be causing a link problem between main query and subquery.
I have tried to put the ifnull into the subquery but still getting jdbc subquery fields without the ifnull function.

SELECT DISTINCT
jiraissue.RESOLUTIONDATE AS jiraissue_RESOLUTIONDATE,
jiraissue.CREATED AS jiraissue_CREATED,
CalculatedField1_Sub.CalculatedField1 AS CalculatedField1
FROM tjiradb_D1_VDB_DSModel.tjiradb.jiraissue jiraissue
LEFT JOIN
(SELECT DISTINCT
TIMESTAMPDIFF(
SQL_TSI_MINUTE,
jiraissue_sub.CREATED,
PARSETIMESTAMP('2014-10-03 00:00:00',
'yyyy-MM-dd HH:mm:ss'))
AS CalculatedField1,
jiraissue_sub.RESOLUTIONDATE AS jiraissue_RESOLUTIONDATE,
jiraissue_sub.CREATED AS jiraissue_CREATED
FROM tjiradb_D1_VDB_DSModel.tjiradb.jiraissue jiraissue_sub
WHERE ((((jiraissue_sub.RESOLUTIONDATE IS NULL)))))
CalculatedField1_Sub
ON (IFNULL(jiraissue.RESOLUTIONDATE, -2147483648) =
IFNULL(CalculatedField1_Sub.jiraissue_RESOLUTIONDATE,
-2147483648))
AND (IFNULL(jiraissue.CREATED, -2147483648) =
IFNULL(CalculatedField1_Sub.jiraissue_CREATED,
-2147483648))

Teiid JDBC queries:

SELECT DISTINCT g_0.`RESOLUTIONDATE` AS c_0, g_0.`CREATED` AS c_1, ifnull(date_format(g_0.`RESOLUTIONDATE`, '%Y-%m-%d %H:%i:%S.%f'), '2147483648') AS c_2, ifnull(date_format(g_0.`CREATED`, '%Y%m-%d %H:%i:%S.%f'), '-2147483648') AS c_3 FROM `tjiradb`.`jiraissue` AS g_0 ORDER BY c_2, c_3

SELECT g_0.`CREATED`, g_0.`RESOLUTIONDATE` FROM `tjiradb`.`jiraissue` AS g_0 WHERE g_0.`RESOLUTIONDATE` IS NULL
