Hi Pavel
Not sure if this will help in your situation but you can try using
"primaryStage.setOnCloseRequest" where you can run any cleanup code needed.
If you want to cancel the close request completely then just consume the
WindowEvent and then later issue Platform.exit() when ready.

Hello all.
JavaFX adds its own shutdown hook. That gives many problems when it is
necessary to work with application,
when system is shutting down, for example, if user presses CTRL+C. The
first problem I described here -
https://bugs.openjdk.org/browse/JDK-8320923
Another problem is that after pressing CTRL+C JavaFX seems not to
respond anymore. For example I've
observed that if after that we try to do Platform.runLater(() -> myCode
is here), then myCode will never execute.
So, it is necessary to check in system, how it is shutting down, if it
is. And this problem creates other problems.
Before opening a feature request, I decided to ask JavaFX developers, if
it possible to disable JavaFX shutdown hook.
I mean, if there is no system property (something like
javafx.shutdownhook.disabled), it will be added, but if I want
to call Platform.exit() manually I want to be able to disable JavaFX
shutdown hook.
Best regards, Pavel
