I see, which really just ends up replacing code like this:

  |    private void addClassAnnotation(EJBContainer container, Class<? extends Annotation> annotationClass, Annotation annotation)
  |    {
  |       log.debug("adding class annotation " + annotationClass.getName() + " to "
  |             + container + " " + annotation);
  |       container.getAnnotations()
  |             .addClassAnnotation(annotationClass, annotation);
  |    }
  | 
where container.getAnnotations() is returning the AnnotationRepository.
