> The ByteBufferDataReader and ByteBufferDataWriter class are more complex than
> necessary:
> - several methods related to reading/writing strings and char arrays are
> implemented but never used by the native task code. Given that the use case
> for these classes is limited to serializing binary data to/from the native
> code, it seems unlikely people will want to use these methods in any
> performance-critical space. So, let's do simpler implementations that are
> less likely to be buggy, even if they're slightly less performant.
> - methods like readLine() are even less likely to be used. Since it's a
> complex implementation, let's just throw UnsupportedOperationException
> - in the test case, we can use Mockito to shorten the amount of new code
