> When we have the following scenario, the the wadl is not properly generated.
> {code:java}
> public abstract class BaseEntity { ... }
> public class Entity extends BaseEntity { ... }
> public abstract class SuperResource<T extends BaseEntity>
> {
>     @POST
>     @Path("/method")
>     public T resourceMethod(T param){ ... }
> }
> @Path("/resource")
> public class ChildResource extends SuperResource<Entity> { ... }
> {code}
> The generation to ChildResource only exposes the methods to {{BaseEntity}} instead of exposing correctly the specialized type {{Entity}}.
> This problem occurs on {{rt/rs/description/src/main/java/org/apache/cxf/jaxrs/model/wadl/WadlGenerator.java}} file when it evaluates generic types. 
> The solution is considering the TypeVariable to specialized types as follow:
> {code:java}
>                 // Line 1047 instead of this
> -                if (theActualType == Object.class && !(genericType instanceof Class)) {
>                  // using the following lines
> +                if ((theActualType == Object.class && !(genericType instanceof Class))
> +					|| (genericType instanceof TypeVariable)) {
> {code}
