Error "Cannot create TypedQuery for query with more than one return" with named queries
---------------------------------------------------------------------------------------

                 Key: HHH-6695
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6695
             Project: Hibernate Core
          Issue Type: Bug
          Components: entity-manager
    Affects Versions: 4.0.0.CR4, 3.6.7, 3.6.8
            Reporter: Oliver Siegmar


The already closed issues HHH-5348 and HHH-6591 only fixed the bug with standard (non-named) queries. Having a query like {code:sql}SELECT NEW org.test.MyClass( 'Foo', 123 ) FROM IrcEvent ev{code} as shown in HHH-6591 used by createQuery(), the bug has been fixed. Using the very same query as a named query by createNamedQuery() this exception is thrown:
