> Problem to generate WADL when a implementattion of generic type is used
> -----------------------------------------------------------------------
>
> Key: CXF-7545
> URL: https://issues.apache.org/jira/browse/CXF-7545
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.1.9, 3.2.0
> Environment: All plataforms
> Reporter: Evaristo Wychoski Benfatti
> Priority: Minor
> Labels: patch
> Fix For: 3.2.0
>
>
> When we have the following scenario, the process to generate 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}
