      Description

      Here is what I did:

      I created two files simple.java and simple1.java with the following contents:

      simple.java:
      ---------
      import simple1.java;

      class demo {
        public static void main(String args[]) {
          Point p;

          p = new Point();
          p.display();
        }
      }


      simple1.java:
      --------
      class Point {
        public int x = 10;
        public int y = 20;

        public void display() {
          System.out.print("Point is at: " + x + ", " + y + "\\n");
        }
      }

      Compile this and you get the following crash: (a number of things are clearly incorrect
      but the crash shouldnt have occurred!)
