Invoke keycloak rest api

Keycloak kc = KeycloakBuilder.builder().serverUrl(authUrl).realm(troveRealm)
                .grantType(OAuth2Constants.CLIENT_CREDENTIALS).clientId(troveApiClientId).clientSecret(troveApiClientSecret)
                .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build()).build();
kc.realm(shireRealm).groups().groups();

Turns out keycloak admin client version 11.0.3 is not compatible with resteasy 3.14.0.Final. Need to downgrade it to 3.9.1.Final.

Check the maven site for compatibility issue.
