JavaFX N is primarily intended for use with JDK N and we also build and test it against JDK N-1 (which is typically what we use as the boot JDK). Anything older than that, including the proposed minimum JDK N-2 (25 in this specific case), is untested.

builds after upgrading gradle to 9.3.0 and openjdk to 25.0.2 on macOS.
