>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 3.0.4, 2.7.15, 3.0.5
>            Reporter: iris ding
> According to JSR-339 spec, section 4.2.1 and 4.2.2, we need follow different sorting
rule for MessageBodyReader and MessageBodyWritter:
> For MessageBodyReader, it is:
>   <h3> 2. Identify the Java type of the parameter whose value will be mapped from
the entity body. Section 3.7</h3>
> describes how the Java method is chosen.
>    <h3>3. Select the set of MessageBodyReader classes that support the media type
of the request, see Section  4.2.3. </h3>
> For MessageBodyWritter, it is:
>   <h3>4. Sort the selected MessageBodyWriter providers with a primary key of generic
type where providers whose generic type is the nearest superclass of the object class are
sorted first and a secondary key of media type (see Section 4.2.3).</h3>
> But in our implementation, we use the same sorting rule:
>  1. compareClasses() ->compareSortedMediaTypes()
> This caused an issue in
> Actually we need to adjust the MessageBodyReader sorting method.
