I have an JavaFX application that creates a new scene with a StackPane. Inside this StackPane, a label and a WebView are being added. When the WebEngine wants to load a page, however, it causes the application to crash without an error message.
I have a Maven project which includes Spring Boot as a parent and also the javafx modules, such as javafx-web as dependencies. I build it with the goal "package" and run the app via java -jar "C:\SomePath\demo\target\demo-0.0.1-SNAPSHOT.jar". As soon as the WebEngine tries to load a given page, the application closes without showing an error message in the cmd.exe.
The WebView is being created and access in the JavaFX application thread - I already checked that.
Here is my class MyApp.jar:
package com.test.demo;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
/**
* JavaFX App
*/
public class MyApp extends Application {
@Override
public void start(Stage stage) {
WebView webView = new WebView();
WebEngine webEngine = webView.getEngine();
webEngine.load("https://stackoverflow.com");
Label l = new Label("this is my label.");
Scene scene = new Scene(new StackPane(webView, l), 640, 480);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
Here is the pom.xml I'm using:

Does anyone know what causes the WebEngine to crash in this example project?
Here are some more details about the JDK and JAVA version I am using:
C:\Users>javac -version
javac 11.0.8
C:\Users>java -version
java version "11.0.8" 2020-07-14 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.8+10-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.8+10-LTS, mixed mode)
Thank you in advance for any help.
With best regards, Husky
