MacOS Big Sur and OpenJFX on Arm Macs

[Scott Palmer]

JavaFX already runs on some Arm-based devices like the Raspberry Pi, so I expect an Arm-based port for new Macs won’t be that big of a job (relatively speaking)

Hopefully by that time there will be a Metal-base rendering pipeline as well. The Metal-based pipeline for Swing seems to be coming along nicely.

I don’t know if Oracle has access to one of the early developer boxes that runs macOS on arm or not. If they don’t, then a Java/Java FX port may not be available on day 1. That being said,  perhaps Rosetta 2 will run the JDK/JRE until a proper port is available. I don’t know if the JIT compiler will work with Rosetta though. If it doesn’t then that certainly makes a proper port more urgent.
