Yes Arjan, I think it's the first reason. We really should work with them to understand what should be added to CDI 2.0 to have it as a first citizen DI in their spec.

I can't find an exact reference anymore, but I somewhat remember that
one of the reasons was also simply that CDI as a general solution
finished late in Java EE 6, while JAX-RS finished earlier and had all
the work for their own DI solution already done.
