   The variable "ok" has a useful value, but you ignore it. If ok<=0,
doesn't that mean end-of-file? Any time ok<1000, you may print up to a
thousand spurious zeros.

   At minimum, you should change this to

   ...
   int ok=m_line.read(b, 0, 1000);
   if (ok>0) {
     out("read a window");
     for (int i=0; i<ok; i++) {
       System.out.println(b[i]);
     }
   } else {
      // close, break, or something
   }
   ...
