The -nowarn flag does not switch off warnings 
in the new javac compiler. Tested win32 build
of JDK1_3 build "L" 23 July.

The following will generated a "deprecated method warning"

public class Test extends Thread {
        public static void main (String args[])
        {
                Test t = new Test ();
                t.start ();
        }
        public void run ()
        {
                stop (); // WARNING
        }
}
