8.0.144 was the last working version

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a Stage and prevent maximize with the following code:
stage.maximizedProperty().addListener((observable, oldValue, newValue) -> {
  if (newValue) {stage.setMaximized(false);} });

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Not to became invisible
ACTUAL -
Became invisible

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Stage stage = new Stage(StageStyle.DECORATED);
FXMLLoader fxmlLoader = new FXMLLoader();
URL location = getClass().getResource("/*Any FXML FILE*/");
fxmlLoader.setLocation(location);
fxmlLoadersetRoot(null);
fxmlLoader.setController(null);
Parent root = (Parent) MainModel.getInstance().fxmlLoader.load();
Scene scene = new Scene(root);
stage.setScene(scene);
stage.setMinHeight(200);
stage.setMinWidth(200);
stage.maximizedProperty().addListener((observable, oldValue, newValue) -> {
  if (newValue) {stage.setMaximized(false);} });
stage.show;
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Using .144 release until now
But not an option anymore because if WebKit Bug.
JDK-8173250

Now, remove code
stage.maximizedProperty().addListener((observable, oldValue, newValue) -> {
  if (newValue) {stage.setMaximized(false);} });

Not sure anymore why i had to prevent it to became maximized.
I think it was caused by a different behavior between OSX and Windows.

Need testing now.
