Just need to make a ByteBuffer serializer and register it with Kryo as default.

-------------------------
brianmartin: I've written most of this but have run into a problem.

ByteBuffer's are often HeapByteBuffer's, which is a private to java.nio. Therefore, it seems like even though ByteBuffer is registered, Kryo goes to the default serializer anyway because HeapByteBuffer is not registered.

I'm not sure what a reasonable workaround for this would be.

patch draft w/ test: https://gist.github.com/3094071


--------------------------
nathanmarz: Is there any sort of reflection trick you could use to get ahold of the HeapByteBuffer class and register it?

--------------------------
brianmartin: Ah, thanks for the tip.

I've submitted a pull request for this. Apologies for not being able to attach the request to this issue (if that's possible).

Let me know if any changes or contributor agreement are needed.
