@Adding hotspot-runtime-dev


a want to restart a discussion/review-process for on old "bug" JDK-5108778.
I created a webrev which is based on the jdk9/dev repo:


To enable a subrepo review/push-process I created a subtask for the
hotspot part of the change which is JDK-8145061.

The earlier mentioned jtreg-test(see below) was dropped due to some
initial misunderstandings.

@Christian: As you initially responded to my first post I want you to
ask if you want to review / sponsor this fix?
