Possible bug? java.nio.Buffer

[Ito Kazumitsu]

java/nio/Buffer.java has the following code:

  Buffer (int capacity, int limit, int position, int mark)
  {
    if (capacity < 0)
      throw new IllegalArgumentException ();

    cap = capacity;
    limit (limit);
    position (position);

    if (mark > 0)      ----(*)
    {
      if (mark > pos)
        throw new IllegalArgumentException ();

      this.mark = mark;
    }
  }

Should'nt the line marked with (*) be "if (mark >= 0)" ?
