----------------------------------
This bug is invalid or had been fixed in the latest release.
While fetching an access token using GOOGLE as provider type and
AUTHORIZATION_CODE flow, OAuthJSONAccessTokenResponse class should be used to
map the response from server. Finally, I was able to use the following code to
successfully retrieve an access token from Google:
OAuthClientRequest request = OAuthClientRequest
.tokenProvider(OAuthProviderType.GOOGLE)
.setGrantType(GrantType.AUTHORIZATION_CODE)
.setClientId("my_client_id")
.setClientSecret("my_client_secret")
.setRedirectURI("registered_redirect_uri").setCode(code)
.buildBodyMessage();
URLConnectionClient oAuthClient = new URLConnectionClient();
OAuthJSONAccessTokenResponse response = oAuthClient.execute(request, null,
HttpMethod.POST, OAuthJSONAccessTokenResponse.class);
System.out.println("Access token:" + response.getAccessToken());
No invalid_request error was received from google.
Hope this helps.
