Erwin Bolwidt commented on HHH-2625:
------------------------------------

Thanks for the patch. That's a really simple and small change.
I actually have a good use for StatelessSessions and I think, if Hibernate supports these StatelessSessions, it should go the whole way and make them first-class citizens.

As a workaround, you can use reflection to set the impl field.

public static Criteria getExecutableCriteria(DetachedCriteria criteria, StatelessSession session) {
        Field implField;
        try {
            implField = DetachedCriteria.class.getDeclaredField("impl");
        } catch (NoSuchFieldException e) {
            throw new Error(e);
        }
        implField.setAccessible(true);
        CriteriaImpl criteriaImpl;
        try {
            criteriaImpl = (CriteriaImpl) implField.get(criteria);
        } catch (IllegalAccessException e) {
            throw new Error(e);
        }
        criteriaImpl.setSession((SessionImplementor) session);
        return criteriaImpl;
    }
