Looking ahead: allow sufficient review time for CSRs before JDK 16 ramp down 1

[Joe Darcy]

Hello,

Looking ahead, there are approximately 10 weeks until JDK 16 ramp down 1 
in mid-December 2020.

This email is an advanced reminder to factor in sufficient review time 
for any projects needing CSRs before getting pushed into JDK 16. Large 
projects, including JEPs, should often use the two-phase CSR process 
(https://wiki.openjdk.java.net/display/csr/Main) rather than the 
one-phase process. The nominal SLA for each CSR phase is one week. To 
accommodate the possibility of needing to respond to feedback from the 
CSR review, I recommend a large project plan for at least three weeks of 
CSR review time ahead of a planned integration date.

Cheers,
