JDK 9 Rampdown Phase 1: Process proposal

Given that the major feature of JDK 9 (modules/jigsaw) still has major
outstanding unresolved issues [1] and the schedule still suggests
feature complete should have been over three months ago (26th May
2016) [2], the schedule on which this email is based is clearly deeply

I am also very uncomfortable with the notion that modules - a complex,
difficult and still highly debated feature - is still far from
complete, and yet about to be rushed to meet an artificial timeline.
