> *NPE on CC flow*
> Whenever I use a Client Credentials flow, i.e. like :
> curl -u PMEvtbd94ca6oQ:_gSNdEM4ELeZ57h8FuVQpQ http://localhost:9080/oidc/oauth2/token
-d 'grant_type=client_credentials'
> I get a NPE in JPAOAuthDataProvider#saveAccessToken, because serverToken.getSubject()
is null when using CC flow.
