For the record, I withdraw my request to put this on hold until [Lazy stub generation](https://bugs.openjdk.java.net/browse/JDK-8231349) is complete.
As discussed offline I agree with pushing this changes first.

Second, when final changes are ready before push, please, ask Oracle engineer to run tier1-3 in our testing infrastructure.
