sun.misc.Signal is internal proprietary API and may be removed

When you use code like the below code segment to intercept user incurred shutdown signal to do some setting before it shuts down, you get this compile-time warning.

SignalHandler handler = new SignalHandler () {
        public void handle(Signal signal) {
            System.out.println("Sutting down....");
            //do some cleaning or setting here
            System.exit(0);
        }
 };
 Signal.handle(new Signal("INT"), handler);
 Signal.handle(new Signal("TERM"), handler);

Warning: sun.misc.Signal is internal proprietary API and may be removed

You may alternatively use the following code to avoid the warning message.

Runtime.getRuntime().addShutdownHook(new Thread() {
      public void run() {
            System.out.println("Sutting down....");
            //do some cleaning or setting here
      }
});
