How can I use the FX2D render option in Java + Processing?

Question

I am doing the tests for a program I have to do with Java + Processing. I imported the core to the dependencies and I was trying to get the best quality possible with the FX2D rendering, but the moment I use it it just crashes (Tried without specifying the rendering option and worked normally) with this exception:

Re-run Maven using the -X switch to enable full debug logging.

The code I am compiling:

package game;

import processing.core.PApplet;

public class GameSketch extends PApplet {

    @Override
    public void settings() {
        fullScreen(FX2D);
    }

    @Override
    public void setup() {
        background(255);
        frameRate(60);
        smooth(4);
    }

    @Override
    public void draw() {
        background(255);
        fill(0);
        textSize(104);
        text("Hello World!", width / 2, height / 2);
    }

    public void run() {
        String[] processingArgs = {this.getClass().getName()};
        PApplet.runSketch(processingArgs, this);
    }
}

I tried importing every library I found of processing in case I was not importing the right one, also changing the "import processing.core.PApplet;" to "import processing.core.*;" but it continues giving the same exception.

How could I use this processing render option in java?

Which version of Processing are you using and which OS (and OS version) ? — George Profenza, Aug 28 '22 at 19:43
I am using Processing 3.3.7 and Windows 11 Home Version 21H2 — Danermar, Aug 29 '22 at 13:25
Interesting: I've done a test using Processing 3.4 on Windows 11 21H2 and from within the Processing IDE it works if I save the GameSketch class (without the package) in GameSketch.java within the sketch, then in setup `PApplet.main(GameSketch.class.getName());` or `PApplet.runSketch(new String[]{GameSketch.class.getName()}, new GameSketch());`. Are you using command line or an IDE outside of the Processing editor ? (perhaps it doesn't have the javafx jars in the class path ?) — George Profenza, Sep 01 '22 at 11:16

The following source code will run in Processing 3.5.4 (or 4.0.1 if you unREM the import) on a Mac. Use cmd-Q to exit the fullscreen.

// Add this for Processing 4:
//import processing.javafx.*;

class GameSketch extends PApplet {

  GameSketch() {  
    PApplet.runSketch(new String[]{this.getClass().getName()}, this);
  }
  
  void settings() {
    fullScreen(FX2D);
    smooth(4);
  }

  void setup() {
    background(255);
    frameRate(60);
  }

  void draw() {
    background(255);
    fill(0);
    textSize(104);
    text("Hello World!", width / 2, height / 2);
  }
}

static GameSketch gameSketch;

void setup() {
  gameSketch = new GameSketch();
}

How can I use the FX2D render option in Java + Processing?
