DER input, Integer tag error in Javapns iOS push notifications sender

Question

We use JavAPNS for sending push notifications to iOS devices. Push notifications to iOS devices are sent and recieved, when I am in Windows or OS X,but when I am in Linux environment this error occurs:

This is my code:

public void run() {
    List<PushedNotification> notifications = new ArrayList<PushedNotification>();
    String keystorePath = "/cert/cert.p12";

    InputStream keystore = this.getClass().getResourceAsStream(keystorePath);

    try {
        //Some code..
       payload = constructMessagePayload();     


        notifications = Push.payload(payload, keystore,"password",
                false, iphoneTargets);
        logger.info("Notification list size:" + notifications.size());
    } catch (CommunicationException e) {
        logger.error("Exception",e);
    } catch (KeystoreException e) {
        logger.error("Exception",e);
    } catch (JSONException e) {
        logger.error("Exception",e);
    }
    for (PushedNotification notification : notifications) {
        if (pn.isSuccessful()) {
            logger.info("Push ok: "
                    + pn.getPayload().toString());
        } else {
            logger.info("Push not ok: "
                    + pn.getException().toString());
        }
    }
}

If I specify absolute path of file everything works, but I want to have it in src/main/resources, not to log into server every time when I need to change file. If I correctly understand this is problem related with private key.Is there a way this to be fixed.What is different in Linux here? Any advices?

Fixed. When use Maven filtering of resources, it treats *.p12 file like a text file. http://johnnywey.wordpress.com/2009/11/04/careful-with-your-binary-resources/
