Cross-platform JavaFX JAR using maven-shade-plugin

Question

I am trying to create a cross-platform JAR which contains:

• a command line application ("Tool")
• a JavaFX application ("Viewer")

I followed the solution of: Maven Shade JavaFX runtime components are missing and I created on Windows a JAR from which I can run both the Tool and the Viewer. I copied it to a Linux machine, and as I can still run the Tool in this way, the Viewer hangs, and does not even prints to the std out.

Here is my pom.xml

simplified Tool.java:

package crossjavafx;

public class Tool {
    public static void main(String[] args) {
        System.out.println("Hello");
    }
}

simplified Viewer.java

package crossjavafx;

public class Viewer {
    public static void main(String[] args) {
        MainViewer.main(args);
    }
}

MainViewer.java

package crossjavafx;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class MainViewer extends Application {

    @Override
    public void start(Stage stage) {
        try {
            System.out.println("Hello from Viewer");
            Group root = new Group();
            Scene scene = new Scene(root, 400, 300);
            stage.setTitle("Hello");
            stage.setScene(scene);
            stage.show();
        } catch (final Exception e) {
            System.exit(1);
        }
    }

    public static void main(String args[]){
        launch(args);
    }
}

I am executing both applications:

java -cp crossjavafx-0.1.0-SNAPSHOT.jar crossjavafx.Tool // works on win and linux
java -cp crossjavafx-0.1.0-SNAPSHOT.jar crossjavafx.Viewer // works on win, hangs on linux 

Edit I have changed 1.8 to 1.11 below.

           <plugin>
                <configuration>
                    <source>1.11</source>
                    <target>1.11</target>
                </configuration>
           </plugin>

Eventually, I got the following error message when running Viewer on Linux:

#
