How can I prevent maximizing a JavaFX window to fullscreen?

I have done this...

myStage.initStyle(StageStyle.UTILITY);

which works fine for removing the maximize button but someone can still double click on the window title bar (in Windows) to maximize the window.

I tried this but it does not fire.

myStage.fullScreenProperty().addListener(new ChangeListener<Boolean>() {
            @Override
            public void changed(ObservableValue<? extends Boolean> prop, Boolean wasIconified, Boolean isIconified) {
                System.out.println("ignore fullscreen");
            }
        });

Is there some other way to consume that event so it has no effect?

Use this code to your stage

myStage.setResizable(false);

Actually you are listening to the wrong property the one that you are looking for is maximizedProperty

Here is the code to disable window maximize :

primaryStage.maximizedProperty().addListener((observable, oldValue, newValue) -> {
            if (newValue)
                primaryStage.setMaximized(false);
        });

it listens for maximize events then checks whether it's actually maximizing through if (newVale) then forces the stage disable maximization.

hope it helps

Constraint the stage size ranges

myStage.setMaxHeight(500);
myStage.setMaxWidth(600);

and probably

myStage.setMinHeight(50);
myStage.setMinWidth(60);

EDIT:
Well, I agree with @kleopatra, window maximizing on double-click is a common behavior on most OS GUIs, sooner or later OS users will be familiar with this. Still restricting stage size will be helpful if your layout gets worse on larger/smaller sizes. And also still want to disable double click behavior, build your own window manager with JavaFX (like an Ensemble app) without depending to one that OS provides.

If you don't want the user to resize the window at all, you can set the stage's resizable property to false.
