Your test case does limit the number of results with: queri.setMaxResults(10). When that line is commented out, the warning is not logged.

More importantly, your named query is on a class that is a mapped superclass.

JPA 2.1, 2.11.2 Mapped Superclasses, says:

"A mapped superclass, unlike an entity, is not queryable and must not be passed as an argument to
EntityManager or Query operations."

Hibernate should throw an exception in this case.
