Review Comment:
Got it. Looking at the `Base64#encode` method, it change the position of the
source buffer. should we just save the position and restore it after the
encoding is done?
```
Encodes all remaining bytes from the specified byte buffer into a
newly-allocated ByteBuffer using the Base64 encoding scheme. Upon return, the
source buffer's position will be updated to its limit; its limit will not have
been changed. The returned output buffer's position will be zero and its limit
will be the number of resulting encoded bytes.
```
