Not an objection, but rather an observation.

This would mean that we have two things that people will refer to as the 
hotspot repository. The jdk10/hotspot top repository and the 
jdk10/hotspot/hotspot repository with the hotspot code. Maybe it would 
be better to stick with hs? Of course, this problem will go away when 
the repository consolidation is in place, so it might be a short-lived 
issue.


Thanks,
