JAXB MessageBodyReader providers not recognized when using generics in a complex inheritance structure in JBoss EAP 6
Issue
At the scenario given below, RESTeasy is not able to find the correct MessageBodyReader for an incoming XML HTTP Body. I have the abstract resource:
public class AbstractResource<T> {
@POST
@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public Response createEntity(T entity) {
return Response.ok("Success!").build();
}
}
Then an intermediary class:
public class OtherAbstractResource<T> extends AbstractResource<T>{}
And two resources test(doesn't work) and test2(will work in any scenario):
@Path("test2")
@Stateless
public class ConcreteClassThatWorks extends AbstractResource<Model>{
}
@Stateless
@Path("/test")
public class ConcreteResource extends OtherAbstractResource<Model> {
}
I deploy my application and test both resources for XML, see:
[wsiqueir@wsiqueir secured-servlet]$ curl -X POST --data '<model></model>' -H 'content-type: application/xml' http://localhost:8080/generics-resteasy/test

[wsiqueir@wsiqueir secured-servlet]$ curl -X POST --data '<model></model>' -H 'content-type: application/xml' http://localhost:8080/generics-resteasy/test2
Success!
Both will work for JSON:
[wsiqueir@wsiqueir secured-servlet]$ curl -X POST --data '{}' -H 'content-type: application/json' http://localhost:8080/generics-resteasy/test2
Success!
[wsiqueir@wsiqueir secured-servlet]$ curl -X POST --data '{}' -H 'content-type: application/json' http://localhost:8080/generics-resteasy/test
Success!
