Subject [jira] [Updated] (OPENJPA-2065) JPA 2.0 Spec. Violation? EntityManager#createNamedQuery(String, Class) bombs with non-entity Class parameter
Date Wed, 26 Oct 2011 17:57:32 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-2065?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Laird Nelson updated OPENJPA-2065:
----------------------------------

               Labels: specification  (was: )
          Description: 
Suppose we have an interface, A.

Suppose we have a JPA-compliant entity class, B, that implements A.

This construction will fail at runtime:

final TypedQuery<A> q = em.createNamedQuery("someNamedQuery", A.class);

Hibernate and EclipseLink both accept this construction.

I don't see anywhere in the JPA specification that the class parameter must denote an entity
type.
