Re: [cdi-dev] explicit bean archives discovery-mode 'annotated'

While we are at it: the ’none’ mode is broken as well ;) Imagine you have a jar in say DeltaSpike with a bean-discovery-mode=„none“. Now let’s run this in CDI-1.1++ containers: all fine jar gets ignored But in CDI-1.0 containers: whoops, due to having a beans.xml at all (marker interface) the container must scan this jar. There is simply no backward compatible way to tell the container that it should ignore a jar.

If a lib wants to support bean-discovery-mode="annotated" then it has to adapt. It would be better if they did not have to but it's too late at this point. >> Another broken case is if any other IoC uses some of these annotations but doesnt rely on scanning.

This was in the end mitigated by only making CDI annotations as bean defining (most likely other IoC won't use CDI annotations) plus introducing bdm="none" mode.
