Ниже приведен код, который хорошо работает с MQ6, но для MQ7 он дает исключение

'package javaapplication1;

import java.io.*;
import java.net.*;
import java.util.*;
import java.util.TimerTask;
 import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;
    import com.ibm.mq.MQQueue;
    import com.ibm.mq.MQQueueManager;
    import com.ibm.mq.constants.CMQC;
class Connectivity 
{
    public static void main(String args[]) throws MQException
    {
       String qManager="";
       int port_num=0;
    int openOptions =  CMQC.MQOO_FAIL_IF_QUIESCING + CMQC.MQOO_INPUT_SHARED;

    MQEnvironment.hostname = "Host_name";
    MQEnvironment.port = port_num;
    MQEnvironment.channel = "Chn_name";
    System.out.println("Connecting to queue manager: " + qManager);
            Hashtable props = new Hashtable();

            // Change the host name to your host name. Leave it as it is if 
            // queue manager is on the same machine
            props.put(CMQC.HOST_NAME_PROPERTY, "Host_name"); 
            props.put(CMQC.PORT_PROPERTY, port_num);
            props.put(CMQC.CHANNEL_PROPERTY, "Chn_Name");

            MQQueueManager qMgr = new MQQueueManager(qManager, props);
    //MQQueueManager qMgr = new MQQueueManager("SW1_QM");

    MQQueue destQueue = qMgr.accessQueue("Q_Name",   openOptions);

    System.out.println("E_RETRY size:" + destQueue.getCurrentDepth());
    destQueue.close();
    qMgr.disconnect();
    }


}'

Я получаю исключение на линии

'System.out.println ("E_RETRY size:" + destQueue.getCurrentDepth ());'

и сообщение об исключении

'MQJE001: Completion Code 1, Reason 2068

Пожалуйста, помогите мне ..
