Hi All,
Am trying to execute this call :
Keycloak keycloak = Keycloak.getInstance("http://localhost:9080/auth",
"master", "admin", "admin",
"security-admin-console");
But am getting the following error :
Exception in thread "main" javax.ws.rs.client.ResponseProcessingException:

What can cause this error ?
Am running this in the admin-client example (the master one) application by
the way in order to have the right dependencies etc.
Thanks for any help.
