Wicket / OAuth2

Hi all,

AFAIS, there is nothing about a OAuth2 client in Wicket out-of-the-box or
through a satellite project...

Does somebody knows a *simple* solution for integrating OAuth2 into Wicket
(like a OAuthWebApplication, or maybe a ready-to-use Filter, just giving
Consumer Key, Consumer Secret URLs), without using spring-security and
still keeping advantage of the role-based @AuthorizeInstantiation
annotation for instance?

Thanks a lot in advance,
Sebastien.
