Re: OpenJFX 9 integration

Hello Emmanuel,

Thank you for your hard work on OpenJFX!

Although I like Plan C, it has more issues like:

  * Circular build-dependency between openjdk and openjfx (or there is already one?)
  * Strange versioning pattern of openjdk rebuilds. (9~b181-5+<openjfx-version> vs 9~b181-5+b1)

Looks like the extensibility of JRE itself has become a bit worse?
