Stuart Douglas resolved AS7-946.
--------------------------------

         Assignee: Stuart Douglas  (was: jaikiran pai)
    Fix Version/s: 7.0.0.CR1
                       (was: 7.1.0.Alpha1)
       Resolution: Done


I changed the processor to only throw a deployment exception if the PU is actually used as an EE interceptor or component.

> 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.
