code: public static void bytes (Object o, TraceComponent tc, byte[] data, int start) {
      int length = 0;
      if (data != null) length = data.length;
      bytes(o, tc, data, start, length, "");
    }
docs: If debug level tracing is enabled then trace a byte array using formatted
  output with offsets. Duplicate output lines are suppressed to save space.
  Tracing of the byte array starts at the specified position and continues
  to the end of the byte array.
  <p>
  @param o handle of the object making the trace call
  @param tc the non-null <code>TraceComponent</code> the event is associated
  with.
  @param data the byte array to be traced
  @param start position to start tracing the byte array
