> The RocksIteratorWrapper is a wrapper of RocksIterator to do additional status check for all the methods. However, there's a typo that RocksIteratorWrapper.*seekToLast*() method calls RocksIterator's *seekToFirst*(), which is obviously wrong. I guess this issue wasn't found before as it was only referenced in the RocksTransformingIteratorWrapper.seekToLast() method and nowhere else.
> {code:java}
> @Override
> public void seekToFirst() {
>  iterator.seekToFirst();
>  status();
> }
> @Override
> public void seekToLast() {
>  iterator.seekToFirst();
>  status();
> }{code}
