Describe the problem.

I am trying to pass extra parameters to the redirect URL after 
authentication/authorization. However there is a class cast exception in 
AuthorizationCodeResponseUrl. 

Looks like a typo where you are casting AuthorizationCodeResponseUrl to 
AuthorizationCodeRequestUrl. Please fix this. If I remove the extra parameters 
that are specific to my app, then it works fine as it never has to set any 
parameters on GenericUrl.

com.google.api.client.auth.oauth2.AuthorizationCodeResponseUrl cannot be cast

I'm using the attached file to do the redirection after 
authentication/authorization and it's working ok.
