How to use P2D, P3D, FX2D with plain Java?

Question

I have only worked with Processing's standard renderer until now. I got a java project where i am working with processing included via maven. Since other renderers might be faster, i wanted to try using another for my current project, but any other renderer fails for me (P2D, P3D, FX2D). Only the default, Java2D works.

Seemed weird to me, so i started another project with nothing in it, just creating an empty frame. I first tried running it in the Processing.exe as a sketch, and it worked:

The Sketch code:

void setup()
{
  size(500, 200, P3D);
}

void draw()
{
}

I then rewrote it into plain java:

import processing.core.PApplet;

public class Test extends PApplet
{

        public void setup() {
        }

        public void draw() {
        }

        public void settings() {
                this.size(500, 200, P3D);
        }

        public static void main(final String[] passedArgs) {
                final String[] appletArgs = { "Test" };
                if (passedArgs != null) {
                        PApplet.main(concat(appletArgs, passedArgs));
                }
                else {
                        PApplet.main(appletArgs);
                }
        }
}

No matter what i tried so far, i keep running into the following exeption:

I am working with Java 17, and already tried to run with Java 8 as i read this might work, but.. it didnt. Is it not possible to run those P2D, P3D, FX2D sketches outside of the processing.exe?

An even better solution to this problem would be to just use the newer processing4. Micycle1 made the processing4-core usable with maven via JitPack: https://github.com/micycle1/processing-core-4
