I'm confused. I thought the reason this wasn't done in the JEP implementation PR is because of refactoring
that was needed because of the usage in this static block and you could not apply the annotation here.
Yet it seems you are doing exactly what was supposed to be impossible with no refactoring.
Can you explain ?
