             Summary: NPE when restarting Fediz OIDC after using dynamic registration
                 Key: FEDIZ-194
                 URL: https://issues.apache.org/jira/browse/FEDIZ-194
             Project: CXF-Fediz
          Issue Type: Bug
            Reporter: gonzalad
            Priority: Trivial


I'm using dynamic registration and I have a NPE on oidc module restart.

The scenario is this one :
 1. I register dynamically a oidc client
     POST to http://localhost:9080/oidc/services/register
 2. I then restart the oidc module (I could restart all tomcat, it should be the same).
     I have the following error on restart :
{code}
idp_1  | Caused by: java.lang.NullPointerException
idp_1  | 	at org.apache.cxf.fediz.service.oidc.clients.ClientRegistrationService.init(ClientRegistrationService.java:418)

{code}


This is because when we create a Client dynamically, client.getResourceOwnerSubject()  is null.


We than have a NPE in c.getResourceOwnerSubject().getLogin();
