Hi all,
With my strong Java EE background, sentences like "IMO CDI lite should be
targeted to Java SE", hurt ;o)
I remember talking with the JAX-RS guys (Java EE), years ago (back in EE6),
and their answer for not adopting CDI was "too heavy". Today, a JBoss
project called JBoss Forge (Java SE) is "dumping" CDI from its internals
because it's too slow (George, could you develop a bit more this topic?).
What do these two projects have in common ? They just need a "light"
dependency injection framework. I was talking to the Forge guys (I think it
was Lincoln) and, basically, they just need @Inject, @Qualifier and
@Produces (the missing one).
My question is : do we need a CDI Lite, or do we need a "fatter" @Inject
(for both SE and EE) ? I think that if we manage to move producers (and
disposers) to JSR 330, then CDI would do the rest, no need for a Ligther
version.
WDYT ?
Antonio
PS : With Antoine we talked to Juergen (co-spec lead od 330) and Patrick
Curran (JCP Chair man) and it looks like another lead could take over 330
(I'm imagining RedHat talking the Lead role on 330). Even a maintenance
release would be doable

Hi guys,
CDI lite is one of the big feature we are expected to deliver for version
2.0. I think it's time to start discussing about its design.
The big picture is to provide a consistent subset of CDI that could be
implemented like Dagger is (code generated with process annotation). This
would allow using CDI in constrained environment like mobile or embedded
devices.
IMO CDI lite should be targeted to Java SE (I don't think it would make
sense for Java EE). So, from a specification perspective, we''l probably
have to split core part in 2 and se part as well (gosh).
I'm not sure regarding API. today they only weight 72 KB, so creating a
subset only for the sake of the weight doesn't make sense. the only reason
would be to have something clearer for the end user. but that could be
tricky.
