EJBCLIENT000021: EJB client context selector may not be changed in JBoss EAP 6

Issue

I'm setting up an ejb client in JBoss EAP 6 server A to call an EJB in JBoss EAP 6 server B and I'm getting this exception

My client code running in JBoss EAP 6 below. Does that mean I can't use programmatic settings, but have to use a properties-file?

Properties props = new Properties();
props.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
props.put("remote.connections", "default");
props.put("remote.connection.default.port", 4447);
props.put("remote.connection.default.host", host); 
props.put("remote.connection.default.username", username);
props.put("remote.connection.default.password", password);
props.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
props.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");

EJBClientConfiguration cc = new PropertiesBasedEJBClientConfiguration(props);

// create and set the selector
ContextSelector<EJBClientContext> selector = new ConfigBasedEJBClientContextSelector(cc);
EJBClientContext.setSelector(selector);
