EventHandler; import The issue is you are attempting to close the Stage from a thread other than the JavaFX Application Thread. maybe if we use singleton pattern , it can run successfully. I've checked on: JavaFX 2. This method temporarily blocks processing of the current event, and starts a nested event loop to handle When working with JavaFX applications, it is essential to know how the system handles launching and closing of an application. When a A JavaFX Stage corresponds to a window in a desktop application. Learn how to listen for close events in JavaFX stages with step-by-step guidance and code examples. When all stages in an application are hidden (or closed if you like, because it is the same Shows this stage and waits for it to be hidden (closed) before returning to the caller. hide, only closes the one Stage (and its descendants, if any). In Swing you can simply use setDefaultCloseOperation() to shut down the entire application when the window is closed.
