Major Description
The jaxrs frontend module needs to keep only core providers, those for supporting the types mentioned in the JAX-RS spec as well as those which do not require external dependencies such as XPathProvider or XSLTJaxbProvider.
The JSONProvider is optional so it needs to be moved. At some later point of time we will group all the optional providers depending on Jettison(there are at least 3 of them are there, JSONProvider, DataBindingJSONProvider, AegisJSONProvider, plus supporting classes) to a standalone module.
