These queries also make Hibernate crash with the same error:
"Select a from EntityA a left outer join a.entityBList b where b.size > 0"
"Select a from EntityA a left join a.entityBList b where b.size > 0"
"Select a from EntityA a full join a.entityBList b where b.size > 0";

Now I'm unsure if those are correct in terms of JPQL and HQL language.
