I’m fully supportive of this approach. I would love to work to get more in to JSR-330, I
just fear the time sink.

Martijn,
I started this thread to discuss wether we should do what you’ve just done or not . I’d
have liked to have Pete input before stepping like this. I guess the decision is taken now
;).
Anyway, thanks for your enthusiasm. It gives good vibes for the coming JSR ;).

we can move on.

sometimes from others considered "Rock Stars" of the Java Community but since
then seemingly resting on their laurels or just too busy counting their stock

those involved in the EC (Martijn, Badr/MoroccoJUG,..) could probably check with the PMO
how to handle a case where the Maintenance Lead of a JSR was not in the position to
continue. I last met Jürgen Höller about a year ago in Copenhagen, so for Pivotal's
part as Co Spec Lead, I guess he or the likes of Josh Long could be best to speak to.
Happy to get you in touch with them if you want.

enhancements you have in mind break the existing API of JSR 330. The scope of CDI 2 to
work in an SE/standalone or more lightweight environment than Java EE environment raises a
good question of package names like " javax.enterprise.inject.*" So maybe there
is room for synergies in a package namespace other than "javax.enterprise" at
least for new things you have in mind.

discussion here.

was to go see what we could add in JSR 330 to make it a true specification that could be
the first module of CDI. My idea at that time was to discuss with JSR 330 owner to see if
we could bring basic concept we have in CDI to AtInject spec. In my mind the main features
would have been:

than javax.enterprise.inject.Instance<T>. That would have included support for
AnnotationLiteral and TypeLiteral as well

resolve beans instance from outside managed beans

to BeanManager from JNDI or CDI class)

> At that time, I contacted Bob Lee without success (didn’t tried Pivotal since I don’t
have contact there). I checked with JCP what could be done if we’d like to see an
evolution of JSR 330 and the owner doesn’t care, there seems to have solutions but I let
it aside since we were in the middle of CDI 1.2 MR at that time.

heard and even if the people leading this would be cooperative, a lot of discussion and
negotiation would be needed to be sure that this new AtInject wouldn’t contain features
incompatible with CDI. So it’d be very time consuming with no guarantee to get what we’d
need at the end.

work than just deciding that we have a specific basic inject « part » in CDI 2.0. Leading
a spec is very time consuming, so it could be better on the paper but will impact CDI 2.0
new features.
