I absolutely agree on the JVM platform, an uber jar file is really quite easy to use and deploy.

You don't need to do JLink for JavaFX. FX requires binary libraries, but you can make "platform specific" uber jars (and, probably, generic uber jars) that bundle correct libraries.

SQLite bundles all of the platforms into a single jar file, for example.

But that's another reason, at least for me, to look at the maven wrapper. Maven will "download the right thing" and not "burden" folks with copies of libraries they don't need. FX binaries can be quite big, particularly if you include WebKit (which I do simply for easy in app documentation, it's just a fat pig of a dependency though).
