----------------------------------

    Summary: JAX-RS runtime needs to exclude matching sub-resources by default if matching resource methods exist  (was: JAX-RS client runtime needs to exclude matching sub-resources by default if matching resource methods exist)

> Consider the request "GET /root/book" and the following code:
> {code:java}
> @Path("root")
> public class Root {
>     @Path("book")
>     public getSub() {return new Sub();}
>     @Path("book")
>     @POST
>     public void addBook(Book book) {}
> }
> public class Sub {
>    @GET
>    public Book getBook() {}
> }
> {code}
> CXF will dispatch the call to Sub.getBook().
> Unfortunately, JAX-RS matching algorithm is currently written such that the call will rejected due to the fact the matching sub-resource is supposed to immediately discarded if the current root has methods matching the same path, even though these methods (such as addBook) has no matching HTTP verb.
> IMHO it is a JAX-RS algorithm limitation and I'm positive at the moment that this issue will be addressed as part of the JAX-RS 2.1 work. However CXF needs to support this behaviour *by default* for CXF to stay on the 'pure' JAX-RS 2.0 path.
> The contextual property to support the users depending on the current CXF approach will be introduced
