TrapExit

object TrapExit

Provides an approximation to isolated execution within a single JVM. System.exit calls are trapped to prevent the JVM from terminating. This is useful for executing user code that may call System.exit, but actually exiting is undesirable.

Exit is simulated by disposing all top-level windows and interrupting user-started threads. Threads are not stopped and shutdown hooks are not called. It is therefore inappropriate to use this with code that requires shutdown hooks, creates threads that do not terminate, or if concurrent AWT applications are run. This category of code should only be called by forking a new JVM.
