Hi Kevin,

Thanks for the update. I think the positive message is that Oracle is
moving JavaFX forward. I also agree that supporting JavaFX on ARM involves
more than just running HelloWorld on the Raspberry Pi.

Having said that, I feel comfortable enough to help out with the ARM port.
The wiki is a great resource, and building the SDK was really easy. The
fact that most code in OpenJFX is shared across all platforms is really
great, it enabled the Android and iOS ports.

Building and hosting the ARM ports can be done in javafxports.org -- that
site will contain an important update soon as well. I think it is important
to have as much (ported) code as possible still on OpenJFX, provided it is
of the same quality as the current code and it passes the reviews.
