Well, the actual JIRA issue talks about CDI specifically. If this
feature is going in solely to solve a CDI problem, then I'm against it
because the problem doesn't exist.

What kind of things does jersey use it for? @Context injected things
only? Or as an injection abstraction? Resteasy does have a feature
like this, but it is a static method that can be used anywhere and
doesn't require a @Context injection to get the service. I also kinda
want to move away from this as I feel that things like Configurable are
filling in the gaps.


FYI, I don't mind you adding this stuff in GIT. It actually makes
things clearer if I see the code first. As we saw with the async stuff,
its pretty easy to rollback.
