DER input, Integer tag error in push notifications sender

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?
