I've set the appropriate versions for Hibernate 5 and added a standalone test case using an H2 database. The error is the same as running inside Oracle.

javax.persistence.PersistenceException: org.hibernate.HibernateException: SqlNode's text did not reference expected number of columns

when I'm expecting a simple query like

SELECT a.*
FROM   a  
WHERE  EXISTS (SELECT '' 
	       FROM   ab intersection 
	       WHERE  intersection.a_id = a.id 
		 AND  intersection.foobar_id = a.foobar_id)

which Hibernate correctly generates when i rename the "id" attribute in "A" to whatever else.
