Api and ApiImplicitParam annotations not read when using resource implementation

Api and ApiImplicitParam annotations are not being parsed/read when they are used in a JAX-RS interface, as in the following example:

@Path("/pet")
@Api(tags = "someTag")
public interface ResourceWithAnnotationsOnlyInInterface {

    @GET
    @Path("/randomPet")
    @ApiOperation(value = "getRandomPet")
    @ApiImplicitParams({ @ApiImplicitParam(name = "petImplicitIdParam", paramType = "query", dataType = "string") })
    String getRandomPet();
}

public class ResourceWithAnnotationsOnlyInInterfaceImpl implements ResourceWithAnnotationsOnlyInInterface {

    @Override
    public String getRandomPet() {
        return "No pet today..";
    }
}

This issue is quite similar to issue #1506
The solution is also similar: use
Api api = ReflectionUtils.getAnnotation(cls, Api.class);

instead of
Api api = (Api) cls.getAnnotation(Api.class);

Noticed in swagger-core version 1.5.8

I will fix this and create a pull request for this

(accidentally closed this issue...)

I created a pull request for this: #1747
