jpa result-set-mapping throw NPE

I can't map query result to POJO.

JPA executes query ok (it trace in logs) but in mapping process throws a NPE.

What is wrong?

NPE:

java.lang.NullPointerException

execution code:

List<TiendaTO> tiendas = entityManager.createNamedQuery("TiendaResources.tiendas_del_usuario", TiendaTO.class).setParameter(1, user.getId()).getResultList();

metadata:

Thanks!

Is com.silyan.meyem.view.visor.tienda.TiendaTO mapped class? If not, then you are facing this problem: https://bugs.eclipse.org/bugs/show_bug.cgi?id=288957

But on the other hand "entity-result entity-class", it kind of makes sense that entity is expected, of course some implementations can support also other classes.
