Jozef Hartinger commented on CDI-132:

This is IMHO completely wrong. Having two classes:

public class Foo {

public class Bar extends Foo {

we end up with two beans:
* Foo named "foo"
* Bar without name

Now suppose we add an extension that does not manipulate bean names at all. For instance:
public class FooExtension implements Extension {

    public void wrap(@Observer ProcessAnnotatedType<Bar> event) {
        final AnnotatedType<Bar> bar = event.getAnnotatedType(); // bar.getAnnotations() contains Named
        event.setAnnotatedType(new ForwardingAnnotatedType(bar)); // just wrap, no change

The container examines the annotated type provided by the extension --> getAnnotations() now contains Named. As a result, we end up with:
* Foo named "foo"
* Bar named "bar"

This is a side-effect of an extension that *does not actually change anything*.

> The spec is not exactly clear about the initial content of AnnotatedType.
> When initially building the AnnotatedType (e.g. before handing it over to the Extensions) we need to pre-fill them with the info from the annotations from the classes.
> Should this AnnotatedType:
> 1.) contain no annotations from superclasses?
> 2.) contain all annotations from superclasses?
> 3.) contain @Inherited annotations from superclasses?
> I think the other questions already got cleared up in CDI-70:
> Should AnnotatedType contain derived public? protected? private? methods/fields from a superclass?
> Imo it should contain all information which would be available by manually parsing any annotations. In other words: it should be possible to completely modify or emulate annotations of a parsed type.
