Adding additional parameters to OAuthBearerClientRequest

[Derek R]

Hi,

Is it possible to add additional parameters to this request?  In order to add 
additional parameters it seems that I need to extend OAuthBearerClientRequest, 
and expose a method to add to the parameters map (protected in 
OAuthRequestBuilder).  Is there an easier way?

Example:
OAuthClientRequest bearerClientRequest = new 
OAuthBearerClientRequest("https://graph.facebook.com/me";)
         .setAccessToken(accessToken).buildBodyMessage();
Is there a way to inject another variable into the body?

Thanks
