Is there an easier way of getting javaFX to work with Java and JAlbum?
Yes. Use Windows 11 or macOS 11.x or 12.x.
I'm not being facetious. You could simply install the latest version of jAlbum, and get down to the business of using
it to produce albums, rather than thrashing around in the arcana of Java and JavaFX versions.
You have chosen to use an OS that you don't seem to be able to tame. You should probably reexamine your reasons for doing so.
