      • systemExit

        public static java.lang.Thread.UncaughtExceptionHandler systemExit()
        Returns an exception handler that exits the system. This is particularly useful for the main thread, which may start up other, non-daemon threads, but fail to fully initialize the application successfully.

        Example usage: 

        public static void main(String[] args) {
   Thread.currentThread().setUncaughtExceptionHandler(UncaughtExceptionHandlers.systemExit());
   ...

        The returned handler logs any exception at severity SEVERE and then shuts down the process with an exit status of 1, indicating abnormal termination.
