Re: java.util.Base64. Encoder and Decoder also seem to be able to work with
ByteBuffer. If you have an array, you can cheaply create a ByteBuffer wrapper
around that array. The now-backing array would be read or written though from
the specific position and up to the specific limit. Would that help?
