Oracle also has an early branch/RDP2 date for their updates. E.g. 12.0.2 is probably branched about now.

This looks better.

The addition I'd like to see is to start the weekly promotions earlier,
so they also happen in the first stage. That would avoid b01 being so
huge. I think that's a good halfway house between proposing entering the
critical fix stage next week and not promoting anything until the end of
May.

That would mean multiple jdk11u-dev->jdk11u & jdk8u-dev->jdk8u merges
from next Wednesday 1st of May through to the final one of May 29:

March 2019: jdk11u-dev repo open (tag: jdk-11.0.4+0)
================= RDP1 =====================================
=     jdk11u tree gets changes by merge from jdk11u-dev    =
============================================================
Wednesday, May 01 2019: First build (tag: jdk-11.0.4+1)
Wednesday, May 08 2019: Second build (tag: jdk-11.0.4+2)
Wednesday, May 15 2019: Third build (tag: jdk-11.0.4+3)
Wednesday, May 21 2019: Fourth build (tag: jdk-11.0.4+4)
Wednesday, May 29 2019: Fifth and final RDP1 build (tag: jdk-11.0.4+5)
================= RDP2 =====================================
= jdk11u tree gets changes only by jdk11u-critical-request =
============================================================
Wednesday, June 5, 2019: First RDP2 build (tag: jdk-11.0.4+6)
Wednesday, June 12, 2019: Second RDP2 build (tag: jdk-11.0.4+7)
Wednesday, June 19, 2019: Third RDP2 build (tag: jdk-11.0.4+8)
Wednesday June 26 2019: Last tag before code freeze (tag: jdk-11.0.4+9)
================= FREEZE ===================================
=            jdk11u sees no public changes                 =
============================================================
Tuesday, July 16 2019: GA (tag: jdk-11.0.4-ga, likely to be jdk-11.0.4+10)

This allows regular testing earlier in the cycle, but without
restricting the process down to critical fixes early.
