on the box ubuntu was installed headless, but x server was added later on.

Swing works correctly on that box, but JavaFX fails with next exception:

We know about this issue and Eva is working on it. This happens when there's a Stage without Scene.

Can you post the source code of the application you used? I think it's irrelevant of the installation of Xserver.
