Thank you.  That worked.

RealmResource.toRepresentation() doesn't include the users. To retrieve the users try the following:

RealmResource realmsResource = keycloak.realm("fms-sso");
List<UserRepresentation> userRepresentations = realmsResource.users().list();

I can create a keycloak instance and get a RealmRepresentation.  The RealmRepresentation looks like I expect it should, matching what I see in the KC console.

When I try to get users or federated users, a null is returned.

Here is a code snip

                                                Keycloak keycloak = Keycloak.getInstance(
                         serverUrl,
                         realmName,
                         username,
                         password,
                         clientId);
                RealmResource realmsResource = keycloak.realm("fms-sso");
                RealmRepresentation realm = realmsResource.toRepresentation();
                List<UserRepresentation> userRepresentations = realm.getFederatedUsers();
                userRepresentations.stream().forEach(this::printUser);
                userRepresentations = realm.getUsers();
                userRepresentations.stream().forEach(this::printUser);

realm.getFederatedUsers();
and
realm.getUsers()

both return null, not even an empty list.

Is there something required before getting the users from a RealmRepresenetation?
