>Description:
Folliwing code come from http://java.sun.com/docs/books/tutorial/essential/threads/timer.html

With a change this call Timer.schedule(TimerTask,long,long)
instead of Timer.schedule(TimerTask,long).
Sun's JVM-1.4b3 works with this code (no exception). 
kaffe-1.0.6 works (no exception).

import java.util.Timer;
import java.util.TimerTask;
public class Reminder {
    Timer timer;
    public Reminder(int seconds){
	timer = new Timer();
	timer.schedule(new RemindTask(),seconds*1000,1000);
    }
    class RemindTask extends TimerTask {
	public void run(){
	    System.out.println("Ohh!");
	    timer.cancel();
	}
    }
    public static void main(String[] args){
	System.out.println("About to schedule task.");
	new Reminder(5);
	System.out.println("Hello world! ...\n");
    }
}
