Subresource Paths are not grouped under Resource Tags

[jbuvv]

Hello!

We are using the following Pattern in our Application:

@Tag("My Tag")
@Path("/myparent")
@ApplicationScoped
class MyResource {
  @Inject MySubResource r;
  @Path("/mysub")
  public MySubResource getMySubResource() { return r; }
}

@ApplicationScoped
class MySubResource {
  @GET
  @Path("/hello")
  @Operation(summary = "myop")
  public String getHello() { return "hi"; }
}

So we have just a single Endpoint '/myparent/mysub/hello'.
I would expect the EP to have the "My Tag"-Tag but instead it has none.

I suspect the Tag is missing because the Tags are not forwarded to the function that processes the subresources:

smallrye-open-api/extension-jaxrs/src/main/java/io/smallrye/openapi/jaxrs/JaxRsAnnotationScanner.java

Line 294 in 2f92735

processSubResource(context, resourceClass, methodInfo, openApi, locatorPathParameters);

Is that the intended behavior?

I'd say this is a bug, also discussed in #1546. Just like a @Tag on a resource method overrides a @Tag on the parent resource class, it would probably make sense to a @Tag on the subresource producer method to override a @Tag present on the sub-resource class.

@Tag order of priority:

1. Directly on resource method
2. On nearest subresource producer method (when operation is in a subresource)
3. On nearest subresource class (when operation is in a subresource)
4. On root resource class
