Review comment:
Could you please use `Objects::requireNonNull` from the standard
library? For example,
```
Objects.requireNonNull(input, "The inputStream is required but null value
was provided");
Objects.requireNonNull(outputStream, "The outputStream is required but null
value was provided");
```
Thank you.
