JavaFX: stage's minHeight considering titlebar's height

问题

I'm currently building a small UI application for personal purpose and I ran into a problem. Here is some code:

public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("ui.fxml"));

    Scene scene = new Scene(root);

    stage.setTitle("My app");
    stage.setScene(scene);
    stage.setMinHeight(608.0);
    stage.setMinWidth(1080.0);

    stage.show();
}

And here's the FXML code assiociated with:

<GridPane gridLinesVisible="true" minHeight="608.0" minWidth="1080.0" xmlns="http://javafx.com/javafx/8.0.112" xmlns:fx="http://javafx.com/fxml/1" fx:controller="my.package.MyClass">
    <rowConstraints>
        <RowConstraints minHeight="500.0" prefHeight="500.0" vgrow="ALWAYS" />
        <RowConstraints maxHeight="108.0" minHeight="108.0" prefHeight="108.0" vgrow="NEVER" />
    </rowConstraints>
</GridPane>

So, my problem is that, at launch, the GridPane will effectively have a height of 608px but is still resizable to a smaller height. Indeed, it will be resizable until the stage will be 608px, including the title bar's height...

The behaviour I would like to have is that my GridPane can't have a smaller height than 608.0.

Do you know any ways to do that? Many thanks in advance!

As @James_D pointed out in a comment, I simply had to modify my code as follow:

public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("ui.fxml"));

    Scene scene = new Scene(root);

    stage.setTitle("My app");
    stage.setScene(scene);

    stage.show();

    stage.setMinHeight(stage.getHeight());
    stage.setMinWidth(stage.getWidth());
}
