Hook params not defined within PHP class

Hi.
Firstly thanks for this plugin.
I’m developing a plugin for handling Paypal payments.
In the main plugin’s file i have code like this:

require 'classes/class.server.php';
add_action('plugins_loaded', array('CRPP_IPN_Server_Class', 'init'));

and in the class.server.php I’ve set up code like this

    class CRPP_IPN_Server_Class extends WP_Plugin_Class
    {
        
        /**
         * Class' instance
         *
         * @access public
         * @var class instance
         */
        static $instance;
    
        /**
         * Init()
         * 
         * Class' instance initialization
         *
         * @access public 
         * @return instance
         * @author Raffaele Candeliere
         */
        static function init()
        {
            is_null( self::$instance ) AND self::$instance = new self;
        
            return self::$instance;
        }
    
        /**
         * __construct()
         *
         * Class' constructor
         *
         * @access public
         * @return void
         * @author Raffaele Candeliere
         */
        function __construct()
        {
            /*
             .
             .
             .
             */
            add_action( 'paypal_ipn_for_wordpress_payment_status_completed', array($this, 'ipn_payment_status_confirmed_handler'), 10, 1);
        }

        public function ipn_payment_status_confirmed_handler($posted) {
            error_log(var_export($posted, true));
        }

Well, the problem is that if I define the hook like this, the $posted parameter doesn’t get populated. I do receive the notification but the $posted var is empty.
Viceversa, if i hook into your plugin directly in my main’s plugin file, like this:

add_action('plugins_loaded', 'crpp_init');

function crpp_init() {
    add_action( 'paypal_ipn_for_wordpress_payment_status_completed', 'crpp_ipn_payment_satus_confirmed', 10, 1);
}

function crpp_ipn_payment_satus_confirmed($posted) {
    error_log(var_export($posted, true));
}

then the $posted param is populated!
I’d like to stick with my (standardized) programming pattern where i confine each functional block of code in the relevant class.
What am I doing wrong in using/registering, calling your hook?
Thanks
