title: Hibernate order by with nulls last
body: <p>Hibernate used with PostgreSQL DB while ordering desc by a column puts null values higher than not null ones.</p>
  
  <p>SQL99 standard offers keyword "NULLS LAST" to declare that null values should be put lower than not nulls.</p>
  
  <p>Can "NULLS LAST" behaviour be achieved using Hibernate's Criteria API?</p>
