> Iris -- What's your plan for the Reply-To headers of changeset notifications?

Based on where the notifications for jdk8 go, these are the default "Reply-to" values for each of the new mailing lists:

  jdk9-changes: jdk9-dev
  jdk9-dev-changes: compiler-dev, core-libs-dev, serviceability-dev, net-dev, build-dev
  jdk9-client-changes: 2d-dev, awt-dev, swing-dev
  jdk9-hs-changes: hotspot-dev
  jdk9-hs-comp-changes: hotspot-compiler-dev
  jdk9-hs-emb-changes: hotspot-runtime-dev
  jdk9-hs-gc-changes: hotspot-gc-dev
  jdk9-hs-rt-changes: hotspot-runtime-dev, serviceability-dev

Does everything look right?

Thanks,
iris
