How to pass a Parameterized CallbackHandler to EJBClientContext properties in EAP6

Issue

• Is there a way to use a Custom CallbackHandler, which has a constructor containing two String arguments (username & password) and passing the CallbackHandler to the EJBClientConfiguration properties as following:

props.put("remote.connection.default.callback.handler.class", "test.SimpleAppCallbackHandler");

Example:

        props.put("remote.connection.default.host", host);
        props.put("remote.connection.default.port", port);
        props.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", false");                 
        props.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
        props.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT","false");
        props.put("remote.connection.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS","JBOSS-LOCAL-USER");
        props.put("remote.connection.default.callback.handler.class", "test.SimpleAppCallbackHandler");

        EJBClientConfiguration ejbClientConfiguration = new PropertiesBasedEJBClientConfiguration(props);
        ContextSelector<EJBClientContext> selector = new ConfigBasedEJBClientContextSelector(ejbClientConfiguration);
        EJBClientContext.setSelector(selector);

• Any such attempt is causing the following exception:
