Avian VS jfx

There's been plenty but they've fallen aside for various reasons.

- GCJ (iirc only pre 1.5-1.6 java support so never with generic versions, not sure if they ever implented JNI but relied on their own so libraries with native bindings had to be manually ported iirc)

- Excelsior JET was a strong option for a long time on desktops up until 2018, main selling point was resistance to decompilation but not sure if they ran afoul of Oracle licensing or couldn't keep up with the accelerated pace of JDK releases in later years.

(The below were options to various degrees for iOS developers)

- Avian VM ( https://readytalk.github.io/avian/ ), opensource and seems to be up but never really saw an uptake or proper debug tooling iirc, seems inactive by now.

- Robo VM was another strong option with strong support for IDE debuggers,etc since it was used by gamedevs and the initial libgdx author was involved in it. Sadly they were sold out to Xamarin shortly before MS bought out Xamarin and then promptly shut down since MS only had interest in Xamarin for their C# iOS/Android toolkits.

- RoboVM forks, luckily RoboVM core was liberally licensed so forks were possible for those working on mobile games with iOS ports even if the tooling wasn't as slick as the official RoboVM project (No idea if any of the open source variants have caught up, it was a bit chaotic initially with many forks).

- Intel had(have?) some AOT compiler for Java that was an option for libgdx developers for a while but RoboVM being more "native" had more eyes and no idea if Intel really had a business case for it's Java things ? (

(Funnily enough, I was actually doing an AOT one during late uni times to write a thesis on game GC's (and hoping to maybe commercialize), then Oracle bought out Sun and I wrote a JS AOT prototype instead. Hearing of Oracle vs Goog it felt sane but Oracle did showcase RoboVM later on so maybe it was silly)

Important message in the release notes: "JavaFX 20 is compiled with --release 17 and thus requires JDK 17 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read."

JavaFX 17 requires at JDK 11 or later (release notes), so the short answer is that you can't do this.

JavaFX has been open-sourced after Oracle dropped it, and it's still in active development (they just released version 19 a month ago, see https://openjfx.io and https://github.com/openjdk/jfx). Also Gluon (https://gluonhq.com) made the toolchain to compile it into native apps for Linux, macOS, Windows, Android & iOS. So with now WebFX compiling it to the web, you get a fully cross-platform UI toolkit that lets you target all major platforms (Desktops, Web, Tablets & Mobiles) from a single Java code base. That's why I think it is interesting, especially for Java developers.
