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

Hi Sergey,

Sorry for the late. I have attached the fix for this problem. The basic idea is to sort the
base provider and application provided provider separately and get candidate from each of
them. Then compare the two candidates and get the final selected one.

Please review, all change are in ProviderFactory.java.

Thanks & Best Regards,

Iris Ding

> This is a CTS testcase, the resource class is like this:   
>    @POST
>     @Path("boolean")
>     public Boolean postBoolean(Boolean bool) {
>     	if(bool){    		 
>     		throw new WebApplicationException(Status.NOT_ACCEPTABLE);
>     	}
>         return false;
>     }
> The application provided provider is like this:
> public class MyReader implements MessageBodyReader<Boolean> {
>     @Override
>     public boolean isReadable(Class<?> type, Type type1, Annotation[] antns, MediaType
mt) {
>     	return type== Boolean.class;
>     }
>     @Override
>     public Object readFrom(Class<Object > type,
>                              Type type1,
>                              Annotation[] antns,
>                              MediaType mt, MultivaluedMap<String, String> mm,
>                              InputStream in) throws IOException, WebApplicationException
{
> 		return Boolean.valueOf("true");        
>     }
> }
> The request
> Content-Type:text/plain
> Accept:text/plain 
> Method:POST
> Body:false
> According to jsr339 section 4.2.4 Standard Entity Providers java.lang.Boolean, java.lang.Character,
java.lang.Number Only for text/plain. Corresponding primitive types supported via boxing/unboxing
conversion.
> An implementation MUST support application-provided entity providers and MUST use those
in preference to its own pre-packaged providers when either could handle the same request.
More precisely, step 4 in Section 4.2.1 and step 5 in Section 4.2.2 MUST prefer application-provided
over pre-packaged entity providers.
> 4.2.1 Message Body Reader
> 3. Select the set of MessageBodyReader classes that support the media type of the request,
see Section
> 4.2.3.
> 4. Iterate through the selected MessageBodyReader classes and, utilizing the isReadable
method of
> each, choose a MessageBodyReader provider that supports the desired Java type.
> It says the entity providers should be sorted by media type firstly then(the media type
is the same) on Section 4.2.1 and step 5 in Section 4.2.2 MUST prefer application-provided
over pre-packaged entity providers. So org.apache.cxf.jaxrs.provider.PrimitiveTextProvider
should be selected as its media type MUST be text/plain and the application provider's media
type is */*.(x/y>x/*>*/*)
> So at this point the CTS expected response code is 200 instead of 406, the application
provided provider should not be chosen.
