Antonio Goncalves commented on CDI-4:

Yes, that reminds me of {{javax.annotation.Resource}}. It got updated in Java EE 6 (it introduced the {{lookup()}} method) and we had to endorse the library for Java SE 6. So yes, there is a bit of tuning when you touch common code like [Commons Annotation|https://jcp.org/en/jsr/detail?id=250].

> Understandably, this is somewhat counter-intuitive to the general concept of observing an event, but there is going to be need for this in an upcoming JBoss project. While it can be done manually, it might be nice to have a built-in API.
