Can you provide a link to the issue in JBS that corresponds to that

That's rather out of scope of the document.

It's focused on changes targeted for JDK 9 which may affect code that 
relies on default, deprecated, removed, unsupported, internal or

OK - could you provide a mock up of what you think it should look like?
