Would DOSGi RI 1.1 work with
or is there any reason it would not?

I'm thinking of adding more supported values to it so that one can say : ""="jaxb,json"
instead of typing class names when setting a "".

(which is Jettison-based) then install either Jettison 1.1 bundle [1] or Jettison 1.2, CXF
2.2.4 (which depends on Jettison 1.1) should accept it too, there's no version range in the
CXF Import-Package for jettison packages
