JavaFX application crashes on Mac when the user switch from it to another app in full screen mode

Question

I don't understand what it can be. For this reason I don't know where to get my hands.

I'm using:

• Java SE 1.8
• JavaFX for the user interface

The condition in which the application crashes:

• The app is showing a modal:

Stage dialog = new Stage();
dialog.setScene(new Scene(root));
dialog.initOwner(loader.getController());
dialog.initModality(Modality.WINDOW_MODAL); 
dialog.showAndWait();

• The user switches from this app to another app opened in full screen.

This is what happens when the error occurs:

1. The application is closed
2. An error appears in the console (I'm pretty sure it's not a java exception)

What is the problem? Does it happen only on Mac? How can I solve it?

Answer 1

I solved this problem by updating to JavaFX 14. I suppose it was a bug of the library.
