When try to iterate over keys/valis via Hot Rod client (RemoteCache), it fails with the following error:

org.infinispan.client.hotrod.exceptions.HotRodClientException: java.lang.SecurityException: ISPN000287: Unauthorized access: subject '<subject>' lacks 'ADMIN' permission

Debugging the server, it shows that DefaultIterationManager.start() retrieves the EncoderRegistry from GlobalComponentRegistry, which requires admin permissions. The retrieval shouldn't ask for admin (in this case).
