[FIXED] Problem with webEngine JavaFX using with swing

Issue

I'm trying to load browser using JavaFX WebEnginge to swing as below

SwingUtilities.invokeLater(() -> InitGUI());

final JFXPanel jfxPanel = new JFXPanel();
panel.add(jfxPanel);

Platform.runLater(() -> {
    WebView webView = new WebView();
    jfxPanel.setScene(new Scene(webView));
    webView.getEngine().load("https://pl.wikipedia.org/wiki/London");
});

Websites shows in my swing application but when I'm moving a mouse on the loaded website IntelliJ throws

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: 'void com.sun.javafx.embed.EmbeddedSceneInterface.mouseEvent(int, int, boolean, boolean, boolean, int, int, int, int, boolean, boolean, boolean, boolean, boolean)'

I should add mouseEventListeners somewhere? Whole GUI is in my Main class, without any buttons, just JLabels and this webView from javaFX. Error occurs only on this webView every time I move mouse/click. Other swing components don't throw anything.

@edit I haven't posted first line of exception

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: 'void com.sun.javafx.embed.EmbeddedSceneInterface.mouseEvent(int, int, boolean, boolean, boolean, int, int, int, int, boolean, boolean, boolean, boolean, boolean)'

Solution

Problem solved

I've added

--module-path /Users/<user>/javafx-sdk-15/lib --add-modules=javafx.controls,javafx.fxml,javafx.web,javafx.swing

in Run>Edit Configurations>VM options
