             Summary: NameBinding annotations on resources are ignored in subresources
                 Key: WFLY-10319
                 URL: https://issues.jboss.org/browse/WFLY-10319
             Project: WildFly
          Issue Type: Bug
    Affects Versions: 12.0.0.Final
            Reporter: Javier Estevez Sanchez
            Assignee: Jason Greene


The following JAX-RS resource exposes two resources via a GET operation: /demo and /demo/subresource. The first one via a sub-resource method, the latter via a sub-resource locator. Additionally, a response filter is binded to the JAX-RS resource class to modify the response. From the JAX-RS 2.0 spec, §6.5.2 Name Binding:
{quote}
Binding annotations that decorate resource classes apply to all resource methods defined in them.
{quote}
However, the binding annotation is not applying to the sub-resource locator method. This happens when the name binding annotation is on the resource class or on the sub-resource locator method. Annotating the sub-resource class or the method within works as expected, though.

Below is the code needed to reproduce this issue:

{code:java|title=The resource and subresource}
@DemoNameBinding
@Produces(MediaType.APPLICATION_JSON)
@Path("/demo")
public class DemoResource {

    @GET
    public String getDemoValue() {
        return "A value";
    }

    @Path("/subresource")
    public DemoSubResource getSubResource() {
        return new DemoSubResource();
    }

    public class DemoSubResource {

        @GET
        public String getDemoValue() {
            return "A value";
        }
    }
}
{code}
{code:java|title=The filter}
@Provider
@DemoNameBinding
public class SomeFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) {
        responseContext.setEntity("A filtered value");
    }
}
{code}
{code:java|title=The binding}
@NameBinding
@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface DemoNameBinding {
}
{code}
