>     ByteArrayOutputStream os = new ByteArrayOutputStream();
>     Output output = new Output(os);
>     kryo.writeClassAndObject(output, info);
>     output.flush();
>     return new Slice(os.toByteArray(), 0, os.toByteArray().length);

> It is not necessary to call os.toByteArray().length as it will result in duplicate copy of the byte array.
