HTMLEditor causes Invocation Target Exception despite modified VM Options working with other JavaFX programs

Question

I have used JavaFX and IntelliJ together before and I am usually able to get it to work. Now I am trying to use HTMLEditor, and despite giving IntelliJ the path to my JavaFX library directory and adding the same instructions I always do to my vm options for the "MyHTMLEditor" class, I still keep getting an Invocation Target Exception.

I have successfully run JavaFX with the same settings on other programs, so I feel like there's probably some module I need to add to the vm options to get HTMLEditor working, but I don't know what.

How can I stop my HTMLEditor object from generating an error?

I am using OpenJFX 12, and Oracle Java 12.

vm options instructions:

--module-path /home/myName/Java_Libraries/javafx-sdk-12.0.1/lib --add-modules=javafx.controls,javafx.fxml

the program:

public class MyHTMLEditor extends Application {

@Override
public void start(Stage stage) {

   stage.setTitle("My HTMLEditor");

   stage.setWidth(650650);
   stage.setHeight(300);

   final HTMLEditor htmlEditor = new HTMLEditor();
   htmlEditor.setPrefHeight(245);

   Scene scene = new Scene(htmlEditor);
   stage.setScene(scene);

   stage.show();
}

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

The Error:

Answer 1

I just needed to add ",javafx.web" to the end of the VM Options instructions.

It's important that there is no space between the comma and "javafx.web".

So, the VM Options instructions become:

--module-path /home/myName/Java_Libraries/javafx-sdk-12.0.1/lib --add-modules=javafx.controls,javafx.fxml,javafx.web
