Class LuckyException

java.lang.Object
  java.lang.Throwable
      java.lang.Exception
          java.lang.RuntimeException
              gate.util.LuckyException

All Implemented Interfaces:

Serializable

public class LuckyException
extends RuntimeException

This exception is intended to be used in places where there definitely shouldn't be any exceptions thrown but the API requires us to catch some, eg: try{ if( a != null){ a.doSomething(); } }catch(NullPointerException npe){ throw new LuckyException("I found a null pointer!"); } Of course the system will never require you to catch NullPOinterException as it derives from RuntimeException, but I couldn't come with a better example.
