Suppose that I use IBM DB2 and I have criteriaQuery, which sets firstResult but not maxResults. For example:

{code}
CriteriaQuery cq = em.getCriteriaBuilder().createQuery(Some.class);
TypedQuery<Some> query = em.createQuery(cq);
query.setFirstResult(1);
query.getResultList();
{code}

this one fails on IBM DB2 with the stacktrace like below. Is it an expected behaviour for DB2 database or rather bug in Hibernate? Can Hibernate JPA implementation set some sensible default for "maxResults" if it's not provided in query?

{code}

What is the SQL query that Hibernate generates?
