Following query is working fine in Hibernate 5.3.7.Final but when i migrated to Hibernate 5.4.0.Final then following query is not working.
Query query = getCurrentSession().createQuery("update Event e set e.user.id=null where e.user.id= :userId");
query.setParameter("userId", userId);

The difference i found in Hibernate 5.4.0.Final appending join in update query
