Orika Mapping to JAXBElement<>

Question

I am using JAXB to generate POJOs from XSDs. Due to some reasons , the generated POJOs have JAXBElement<CustomObject> as property.

public class ResponsePackageType{

   protected JAXBElement<? extends ResponseType> response;
   ....
}

Multiple classes is extending ResponseType but I am only interested to map one type of it, and Orika is having problem recognizing this property.

My code:

JAXBElement<ResponsePackageType> feed = (JAXBElement<ResponsePackageType>) unmarshaller.unmarshal(new FileInputStream( "input.xml" ));

MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();

Type<JAXBElement<ResponsePackageType>> respPackageType = new TypeBuilder<JAXBElement<ResponsePackageType>>(){}.build();

Type<JAXBElement<SpecialResponseType>> spRespType = new TypeBuilder<JAXBElement<SpecialResponseType>>(){}.build();

mapperFactory.classMap(respPackageType, respPackageType)
        .fieldMap("response", "response")
        .aElementType(spRespType )
        .bElementType(spRespType )
        .add()
        .byDefault().register();

MapperFacade mapper = mapperFactory.getMapperFacade();

mapper.map(feed, objectFactory.createResponsePackage(null));

Exception:

Exception in thread "main" java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.TypeVariableImpl cannot be cast to java.lang.Class

How do I go about to solve this issue ?? Should I use propertyResolverStrategy ?
