     Sorry, but I believe we're beyond this point. We (those of us who
want to use Guice and Spring) have pretty much established that the
Jersey 2.0's design prevents us from using Guice and Spring. The only
way we will solve this problem is through open dialogue (on the mailing
list or online chat). The very first thing we need to establish is what
to do on a design level. Creating push requests beforehand is a waste of
everyone's time.

I don't understand. Both Guice and Spring implement JSR-330. What do
Jersey users gain by the forced use of HK2 as the sole DI implementation?

I totally agree. What I disagree with is JAX-RS (and Jersey more
specifically) mandating specific DI behavior. I argue that JAX-RS should
not discuss DI at all. Jersey should provide building blocks needed by
DI integrators so that end-users can use HK2, Guice, Spring, or whatever
else they wish without having to learn yet another DI framework.
