Martin Kouba commented on CDI-420:
[~emilyj] This will not help. Right now, a class is discovered if it has a bean defining annotation *&&* is not excluded (for an implicit bean archive). In other words, the container first tests whether a class has a bean defining annotation and if it has, then container applies filters. We would have to modify the wording in an incompatible way. Also we would have to specify what happens if include/exclude are matched at the same time.
> add a bean-discovery-mode 'scoped'
> Key: CDI-420
> URL: https://issues.jboss.org/browse/CDI-420
> Project: CDI Specification Issues
> Issue Type: Bug
> Components: Packaging and Deployment
> Affects Versions: TBD
> Reporter: Mark Struberg
> Fix For: 2.0 (discussion)
> This is for some future CDI release.
> We currently only have 3 bean-discovery-modes
> * none
> * all
> * annotated
> The spec also currently says that ProcessAnnotatedType will only get fired (12.4) for
> • each Java class, interface or enum deployed in an explicit bean archive, and
> • each Java class with a bean defining annotation in an implicit bean archive.
> • each session bean
> Which means that we do not get the ProcessAnnotatedType (PAT) event for any class in an 'annotated' or 'implicit' BDA which does _not_ have a bean defining annotation.
> It might be useful to fire the ProcessAnnotatedType for all classes, but do not pick them up as Beans if they (after PAT) do not have a valid scope. Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing.
> I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea...
