First revision of an SPI in 0.3 of Jersey. See Marc's blog entry detailing the SPI and a Spring example (source code here).
Investigate improved Spring integration and look more closely at Web Beans (see Gavin Kings series of blogs on introducing Web Beans).
Unify component instantiation model so that instantiation of resource classes and other types of component (such as message body readers and writers) can defer to an IoC framework.
