I'm curious if this is fixed?

> I've found a strange issue with the @SetupRender annotation when used in a class hierarchy.
> Typically, in java 2 classes within a hierarchy can have the same signature for a private method and not effect each other, so I would expect this to be the case when both of these private methods are annotated with @SetupRender. Therefore the output for case 1 and case 2 (below) should be the same and print both messages "setupRender2", "setupRender1".
> However case 1 only prints "setupRender2" meaning it somehow overwrites the method in it's implementing class.
> This is concerning because
> 1. there should never be a requirement that a sub-class knows of it's super-classes implementation
> 2. if hierarchy does come into play, the subclass should override the super class.
> CASE 1:
> ------------------
> public abstract class StartBase {
>    @SetupRender
>    private void init() {
>        log.debug("setupRender2");
>    }
> }
> public class Start extends StartBase {
>    @SetupRender
>    private void init() {
>        log.debug("setupRender1");
>    }
> }
> CASE 2:
> ------------------
> public abstract class StartBase {
>    @SetupRender
>    private void init2() {
>        log.debug("setupRender2");
>    }
> }
> public class Start extends StartBase {
>    @SetupRender
>    private void init1() {
>        log.debug("setupRender1");
>    }
> }
