@arnaudroger Thanks for the contribution! It seems a cool feature.
But I have some questions. Can I ask you to take a look at them?

This static method returns ByteBuffer not ByteBufferInput

It doesn't seem to me that this method is related to ByteBufferInput.
@xerial Do you think this is the right place to put the method in?

We can make DirectBufferAccess a public class instead of adding this method.

Actually this location is a bit weird.

As you might notice since this method doesn't have @Override annotation, Jackson doesn't support this kind of API, I think.
How do you use this method via Jackson's API? It would be great, if you add some unit tests to make it clear 😺

I use the MessagePackFactory directly, currently using reflection.
Useful to parse message coming in from netty for example without creating a lot of garbage.
Also expose the method to create a parser from a sub array.
