code: public static void bytes (TraceComponent tc, byte[] data) {
      int length = 0;
      if (data != null) length = data.length;
      bytes(null, tc, data, 0, 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.
  <p>
  @param tc the non-null <code>TraceComponent</code> the event is associated
  with.
  @param data the byte array to be traced
