Having WSO2 API Manager 2.1.0 and WSO2 IS 5.3.0 KM (with prepackaged Key Manager) I set up the Key Manager as described in the documentation.
The main intention is authenticate and authorize users with other federated IdPs and add some authorization capabilities. My assumption is that users auhorized with WSO2IS will receive an OAuth token valid for the defined APP and API.
So far all on localhost with IS offset 1. I created an API, an application and that is usable from the API Store.
When trying to authorize a client through WSO2 IS using the code grant_type authorization:
https://localhost:9444/oauth2/authorize?response_type=code&client_id=KJTbkbFmcDvslo2fjhzfQkaBH3Ea&redirect_uri=http%3A//localhost%3A8080/test2/callback
I am asked for credentials and authorization grant (looks ok) and then I receive an exception on IS:
[2018-03-27 10:43:51,822] ERROR {org.apache.catalina.core.StandardWrapperValve} - Servlet.service() for servlet [OAuth2Endpoints] in context with path [/oauth2] threw exception

What I assume I misconfigured some endpoint, however - any idea which service is invoked by the OAuth2AuthzEndpoint implementation or potential cause for this exception?
