Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The following code:

public class Main {

        public static void main( String[] args){
            String s = null.toString();

            System.out.println("DONE");
        }
    }

gives

Exception in thread "main" java.lang.NullPointerException
