TrapExit

object TrapExit

This provides functionality to catch System.exit calls to prevent the JVM from terminating. This is useful for executing user code that may call System.exit, but actually exiting is undesirable. This file handles the call to exit by disposing all top-level windows and interrupting all user started threads. It does not stop the threads and does not call shutdown hooks. It is therefore inappropriate to use this with code that requires shutdown hooks or creates threads that do not terminate. This category of code should only be called by forking the JVM.
