   Correction.   
      
   It is not HQL but JPQL.   
      
   The "SELECT ..." is identical in HQL and JPQL.   
      
   Both the API call and the naming of variable clearly indicates   
   that is JPA not Hibernate API.   
      
   I always test with Hibernate as JPA implementation, but standard   
   API!
