Draft process JEP: JDK Release Process

[mark.reinhold at oracle.com]

We’re fast approaching the Rampdown Phase One milestone for JDK 11 [1].
In preparation for that phase, and the phases that follow, I’ve updated,
generalized, and consolidated the various process pages that we used for
JDK 10 [2] into a draft process JEP for use with JDK 11 and beyond:

  http://openjdk.java.net/jeps/8205352

To ease understanding I refactored the text to present one set of
actions whose parameters are adjusted for each phase, but the intent
is that the guidance given here is essentially the same as that spread
across the JDK 10 process pages.

Comments welcome!
