In a Java 17 modular project, the demo cannot be run and the resource files cannot be loaded correctly.

[shenbinglife]

I encountered an error when running the sample code and spent a lot of time learning about Java module-related knowledge. I determined that it is impossible to obtain resource files through ClassLoader and recommended using class.getResourceAsStream instead. Can someone provide an answer? Is this my problem?

Code Version： Java17 + tilesfx 17.1.15

package com.example.javafxdemo._1_TilesFX;

import eu.hansolo.tilesfx.Demo;

class TilesfxDemo {
    public static void main(String[] args) {
        Demo.main(args);
    }
}

Exception in Application start method

It is a problem with modules in general, loading resources of other modules can be difficult to impossible when not using a class loader of the module where the resource sits in. I don't know if tilesfx is prepared for this.
