> Key: CXF-6307
> URL: https://issues.apache.org/jira/browse/CXF-6307
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.0.3
> Environment: Windows
> Reporter: Neal Hu
> Fix For: 3.1.1, 3.0.6
>
>
> 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.
