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

             Summary: MessageBodyReader and MessageBodyWritter should follow different sorting
rule
                 Key: CXF-6412
                 URL: https://issues.apache.org/jira/browse/CXF-6412
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.0.5, 2.7.15, 3.0.4
            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 https://issues.apache.org/jira/browse/CXF-6380.

Actually we need to adjust the MessageBodyReader sorting method.
