In the standard Jedis interface, methods that take byte arrays as a parameter usually return byte arrays.
This is the case in Jedis.hgetAll(byte) but not in Pipeline.hgetAll(byte) which I need in my project.
I fixed that in my commit.
I did not fix other methods, at least not for now.
Pipeline.hgetAll(byte) now returns Map<byte,byte>
