A getter whose implementation happens to return a subtype in a non-exported package does not allow the caller of that getter to access any methods in the non-exported class (even public ones).

yes it can:

--add-opens javafx.graphics/com.sun.javafx.application.preferences=andy_test



        var platformPreferences = Platform.getPreferences();
        var colorSchemeProperty = platformPreferences.colorSchemeProperty();
        Method m = colorSchemeProperty.getClass().getMethod("updateEffectiveValue");
        m.setAccessible(true);
        m.invoke(colorSchemeProperty);
