JPA Metamodel: EntityType.getName != @Entity.name
-------------------------------------------------

                 Key: HHH-5709
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5709
             Project: Hibernate Core
          Issue Type: Bug
          Components: metamodel
    Affects Versions: 3.6.0
            Reporter: Tomasz Blachowicz


I was working recently on the implementation that uses JPA2 meta-model. It was rather surprise to me when I found out that name of the entity on {{EntityType}} is different than name of the entity specified with {{@Entity}} annotation.

The specification is not explicit about the entity names, so it could be interpreted differently, but I think it is reasonable to implicitly assume that entity name specified with {{@Entity}} is used as entity name with JPA2 meta-model.

*10.1 Entity*
The {{Entity}} annotation specifies that the class is an entity. This annotation is applied to the entity
class.

The {{name}} annotation element specifies the entity name. If the {{name}} element is not specified, the entity
name defaults to the unqualified name of the entity class. This name is used to refer to the entity in queries.

{code:java} 
@Documented @Target(TYPE) @Retention(RUNTIME)
public @interface Entity {
String name() default "";
}
{code}

I know that in Hibernate the entity name if FQN of persistent class and the abbreviated name (without the package) can be *only* used within the HQL queries. I guess this was OK prior JPA2 when there was no such think like meta-model.

This topic has been already discussed several times, but I couldn't find any discussion in the context of JPA meta-model, thus I've decided to create a new ticket. The other issues related to this topic are: HHH-4375, HHH-2597 and HHH-4465.
