Does jersey bundle import package named com.sun.xml.bind.annotation? If
not, how do you expect it to be able to load a class from that package
which I assume is exported by jaxb-2.2 bundle. Mind you, all Java EE
applications have an equivalent of DynamicImport-Package: *, so they can
load classes from any exported package.
