How to keep follow up fixes with the original ?

[David Holmes]

It has happened again that a broken fix, for which there was a quick 
follow up fix, has been pushed to the master without the follow up fix 
going with it. So now everyone will potentially be impacted by the bad 
fix as it propagates back down to all the forests :(

Bad fix:

https://bugs.openjdk.java.net/browse/JDK-8073634

Follow up:

https://bugs.openjdk.java.net/browse/JDK-8077563

We need something in place to ensure this doesn't happen!
