Persistence annotation processing is overly restrictive  
---------------------------------------------------------

                 Key: AS7-946
                 URL: https://issues.jboss.org/browse/AS7-946
             Project: Application Server 7
          Issue Type: Bug
          Components: JPA / Hibernate
    Affects Versions: No Release
            Reporter: Marius Bogoevici


If a deployment contains classes bearing the @PersistenceContext annotation, the annotation processor will fail the deployment if a persistence unit is not found. While this is correct for classes which are a target for container-driven injection, the application may contain annotated classes that are not injection targets according to the Java EE specification. This is not illegal according to the specification.

To wit, a Spring application may use @PersistenceContext for performing Spring-driven injection of Spring-managed entity manager factories. 
In the past, such applications could have used the 'metadata-complete' attribute in web.xml, but this does not seem to work anymore. 

Regardless, of that, the server could adopt a more lenient approach, by failing the injection only when a managed bean is actually injected with a non-existent PU/PC reference.

The other variant would be to restrict validation to classes which are actual injection targets according to the Java EE specification.
