I've taken a look at the discussion on the JBS issue again. I'm not sure why it was determined that this change should be applied to tip. I've tried to build locally for JDK tip and JDK15, and there is no uninitialized warning. There is a link in the JBS description explaining where the warning is disabled.

I think this issue should be closed, and I'll update https://github.com/openjdk/jdk11u-dev/pull/489.
