org.hibernate.orm.test.hql.ASTParserLoadingTest.testComponentNullnessChecks org.hibernate.orm.test.hql.ASTParserLoadingTest.testMultipleRefsToSameParam
Both tests try to use null a parameter value
s.createQuery( query ).setParameter( 1, null )
Which results in
java.io.IOException: JZ0SL: Unsupported SQL type 0.
changing null to string "null" in tests seems to fix failure (just experiment, I have no idea what would be correct fix)
