HEADS-UP: Jigsaw is coming for FX 9

[Kevin Rushforth]

We are preparing for the upcoming Jigsaw integration [1] and I wanted to 
give a brief heads-up concerning the steps leading up to this.

* As an interim step we will start building FX with a pre-Jigsaw version 
of JDK 9 (likely build 109) [2]

* I will send out a webrev soon with the changes for JDK 9 based on the 
then-current jake sandbox [3]

* I will integrate the FX 9 Jigsaw changes the same week (for the same 
build) that the Jigsaw changes go into JDK 9

The target for the integration is later this month, so we plan to do the 
first two steps within the next week: the webrev will likely go out on 
Monday and the upgrade to JDK 9 will probably be next Thursday, if we 
encounter no problems.
