AccessTokenService returns reponse with lower case and underscores

Hi all,

Merry Xmas to everyone.

Just a quick question before I leave work, I found that in Oauth2 CXF
2.7.8,
the accessTokenService returns response like this:

Payload:
{"access_token":"8cb4a86829b70fdf3567ff49c1dba46","token_type":"bearer","expires_in":3600}

Everything in lower case and underscores.

All of our other services use camelCases. Is there an easy way to configure
the output?

We are using JacksonJsonProvider BTW.

Cheers,

Jason
