Well - I am not sure I understand what said verbiage means then.
Assuming:

   byte[] bytes = ....;

   var b1 = ByteBuffer.wrap(bytes);
   var b2 = ByteBuffer.wrap(bytes);
   var b3 = b1.asReadOnly();

   b2.put(1, b1, 0, len-1);
   b1.put(1, b3, 0, len-1);

wouldn't any of these put you in the exact same troublesome
situation as:

   b2.put(1, b2, 0, len-1);

cheers,
