TODO

3.x

* MVC: QueryParam annotation vs PathParam try to figure it out them and make optional (update open api)
* MVC: introduce BodyParam
* MVC: Add *Param annotations a statusCode attribute
* Add Response for script and MVC
* map exception names to HTTP Status Code (Forbidden => 403, Unauthorized => 401, etc...)
* review toString on Value API (removal of QueryStringValue?)
* tests and coverage

Jetty close exception:
