HEADS-UP: Proposal to bump the minimum boot JDK for FX to JDK 10

[Kevin Rushforth]

I created a pull request [3] for this, and discovered that the CI builds 
for the GitHub sandbox are using JDK 9.0.4. Michael Ennen is fixing this 
by switching both the Travis and Appveyor CI builds to use JDK 10 [4].

Given the disruptive nature of bumping the minimum, I think it is wise 
to wait another day or two before taking any action on my proposal to 
bump the minimum (we can and should still proceed to upgrade the CI 
builds to use JDK 10). This will give others who might have concerns a 
chance to comment.

Comments?
