Just a reminder that this happens in just over one hour from now.

We will pick a build just after the deadline and run a series of tests on it (tiers 1-3) before adding the tag jdk12+0. Once that is done the JDK 11 stabilization repo will be created. 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.
