I'd just like to say thanks for making jdk/jdk10 available publicly and I hope
this continues beyond the first stage, and also for future releases under the
new model.

Having 8u releases disappear from public view in stage 2 and only re-appear
at GA has introduced delays in making these releases available in downstream
