This is wonderful. I'm looking forward to playing around with JavaFX. Being able to compile that to a native image is huge! It would effectively invalidate the Electron approach of building "native" applications.
However bear in mind you can already bundle JavaFX and the JRE together into native installers for each platform that don't require a JRE or JVM, and don't mention Java anywhere, using the javapackager tool. I've used it several times, it works well enough.
