If folks do that then, the hgupdater will auto create a
JDK11 backport until the updater is switched to JDK12.
It is better to manually update the 'fix version' for
these pushes from '11' to '12'. Then we don't have to
deal with errant/premature JDK11 backports...

Please note however that changes pushed to jdk/jdk now will be pushed to JDK 12. They will not go into JDK 11 unless manually backported. Please update the fix version in JBS before pushing.

Running the tests will take a few hours so have patience and please do not push any changes intended for JDK 12 until the tag has been pushed. I will keep you updated of our progress.
