// How to catch All Exceptions including those from the AWT Event thread.
// Step 1: register a handler class in your main()
//
// System.setProperty("sun.awt.exception.handler", "YourHandler");
//
// Step 2: implement your handler class.
//
// public class YourHandler {
//   public void handle(Throwable thrown) {
//     eat the exception without dumping to the console.
//   }
// }
