code: @Override
      public void reset() throws IOException {
          abortIfNeeded();
          in.reset();
          renewCipherLite();
          resetInternal();
          hasBeenAccessed = false;
      }
docs: Resets back to the very beginning of the stream.
  <p>
  Mark and reset is currently only partially supported, in the sense that,
  if the underlying input stream supports mark-and-reset, this input stream
  can then be marked at and get reset back to the very beginning of the
  stream (but not anywhere else).
