B4J Question Headless JavaFX in Console App

It does work, but not how you seem to think it does.
It is still a UI application; it just doesn't attempt to use any graphics output.
It's the same single threaded Javafx loop running (bad for servers), as a normal Javafx application.

It can still be useful as a console application that is started by the server for specific tasks. It was quite difficult to do with a regular UI app on Linux server: https://www.b4x.com/android/forum/t...-as-part-of-a-server-solution.123704/#content

Starting a program with xvfb-run is slow.

I think the headless mode now solves this problem. I can let the server starts a UI app for processing.
