[cdi-dev] ProcessAnnotatedType question related to Seam-Config

Currently tracking down why seam-config sometimes does not work work OWB.

Seems that the issue is that OWB and Weld does tread AnnotatedTypes registered with BeforeBeanDiscovery in a different way.

Assume we have the following class in a BDA:


public class Doodings {

and you have a seam-beans.xml config  for it too

Then seam-xml will add an AnnotatedType for it in @Observes BeforeBeanDiscovery. So far so good.

Later in the class scanning, when scanning Coodings.class, we (Apache OpenWebBeans) recognizes that the class already has a prepared AnnotatedType and use that for the system event. Apparently Weld does things different and creates a fresh AnnotatedType purely based on the native class!
That's the reason why seam-config in weld has to veto the freshly scanned type to prevent double existence of Bean<Doodings>, and in OWB this hack causes a problem...

I think there is room for improvement in the specification of AnnotatedTypes in the CDI spec ... 

The behaviour must get clarified imo, wdyt?
