[resteasy-dev] XmlSeeAlso question

Hi, I was trying to test @XmlSeeAlso, which is intended to work as such: @XmlSeeAlso(SubType.class) public class SuperType {} public class SubType extends SuperType {} @Path("/") public class Controller {  @GET  public SuperType get() {   return new SubType(); } } So that the marshaller knows to serialise it as a SubType instead of the declared SuperType. But I can't get the JAXBXmlSeeAlsoProvider provider to be invoked, because in ServerResponseWriter we do this:          Class type = jaxrsResponse.getEntityClass();          Type generic = jaxrsResponse.getGenericType();          MessageBodyWriter writer = providerFactory.getMessageBodyWriter(                type, generic, annotations, mt); And `type` is obtained by doing entity.getClass() (so it is SubType) while `generic` comes from the method declaration (it is SuperType). And JAXBXmlSeeAlsoProvider.isReadWritable() uses the Class to ask if it has the @XmlSeeAlso annotation (it does not, because it's the SubType class). All in all, it works, because we fall back to not needing @XmlSeeAlso since the class points to the subtype, but the generic type will point to the superclass and so they're really two different types. Is this a bug?
