Paginator query doesn't work using Oracle

Ive build a dql query using the queryBuilder and I've passed the queryBuilder to the Paginator object. The sql query failed.

here is the sql query that get executed:

SELECT a.*
FROM
(
SELECT DISTINCT ID0
FROM
(
SELECT
f0_.id AS ID0, f0_.title AS TITLE1,
f1_.id AS ID2,
f2_.id AS ID3, f2_.first_name AS FIRST_NAME4, f2_.middle_name AS MIDDLE_NAME5, f2_.last_name AS LAST_NAME6, f2_.phone AS PHONE7, f2_.url AS URL8,
f2_.email AS EMAIL9, f2_.profile AS PROFILE10, f2_.created_date AS CREATED_DATE11, f2_.last_updated_date AS LAST_UPDATED_DATE12,
f2_.object_status_id AS OBJECT_STATUS_ID13, f2_.published_date AS PUBLISHED_DATE14, f2_.publishing_status_id AS PUBLISHING_STATUS_ID15,
f3_.id AS ID16, f3_.title AS TITLE17, f3_.start_date AS START_DATE18, f3_.end_date AS END_DATE19,
f4_.id AS ID20, f4_.name AS NAME21,
f5_.id AS ID22,
c6_.id AS ID23,
d7_.id AS ID24
FROM fo_deal f0_
INNER JOIN fo_deal_role f1_ ON f0_.id = f1_.deal_id
INNER JOIN fo_people f2_ ON f1_.people_id = f2_.id
INNER JOIN fo_position f3_ ON f2_.id = f3_.people_id
INNER JOIN fo_company f4_ ON f3_.company_id = f4_.id
LEFT JOIN fo_people_asset f5_ ON f2_.id = f5_.people_id
LEFT JOIN co_asset c6_ ON f5_.asset_id = c6_.id
LEFT JOIN ds_record d7_ ON c6_.ds_id = d7_.id
WHERE f2_.object_status_id <> 3
AND f2_.publishing_status_id = 2
ORDER BY f0_.published_date DESC
) AS _dctrn_result
) a
WHERE ROWNUM <= 3

It seems that oracle doesn't accept the AS _dctrn_result. if I remove the AS _dctrn_result in the query, the query works and I get the proper information.
