Question

Found this bug in hibernate HHH-5419

I need to understand how I can replace Root element for type with composite key for example with asterisk.

Update hibernate, and use JPQL not an answer.

Answer 1

Never mind.
Replaced query for compound key with it:

    CriteriaBuilder qb = entityManager.getCriteriaBuilder();
    CriteriaQuery<Long> cq = qb.createQuery(Long.class);
    Root<T> root = cq.from(entityClass);
    if (root.getModel().getIdType() != null)
        cq.select(qb.count(root.get("someAnotherAttribute")));
    else
        cq.select(qb.count(root));
