There is no workaround for JDK-8324327

[PavelTurk]

Hello all.

This is about https://bugs.openjdk.org/browse/JDK-8324327 .

Andy Goryachev wrote in comment "Change to the default constructor and the issue 
disappears".
I don't see that using default constructor solves the problem. I tried the 
following code :

public class JavaFxTest7 extends Application {

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

    @Override
    public void start(Stage primaryStage) {
        VBox root = new VBox();
        ColorPicker picker = new ColorPicker();
        root.getChildren().addAll(picker);

        var scene = new Scene(root, 400, 300);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

and I have the same bug.

JavaFX: 23-ea+3
Java: 21.0.2
OS: Ubuntu 20.04.3 LTS

So, ColorPicker is always broken.

Best regards, Pavel
