This may be a case of user shooting himself inthe foot, but compiler allows unlimited instances of class. Maybe compiler can issues a warning.

class Recurse<T>
{
    static int count = 0;

    public Recurse() {
      count++;
      System.out.print(count + " ");
      System.out.println(this.toString());
    }
  public Object nest(int n)
  {
    if (n == 0){
          return this;
    }
    else {
      return new Recurse<Recurse<T>>().nest(n - 1);
    }

  }
  public static void main(String[] args)
  {
   int c = 250;
   if (args.length > 0)
    c = new Integer(args[0]).intValue();

     Recurse<String> cs = new Recurse<String>();
     cs.nest(c);
