Java.io.IOException：使用openSMPP库发送SMS时，将报告未连接，有人可以回答这个问题吗？

Question

@RequestMapping(method = RequestMethod.GET, value = "/test")
@ResponseBody
@ApiOperation(httpMethod = "GET", value = "测试apo", notes = "")
public void testMail(@RequestParam(name = "host", required = false) String host,
                     @RequestParam(name = "port", required = false) String port,
                     @RequestParam(name = "userName", required = false) String userName,
                     @RequestParam(name = "password", required = false) String password,
                     @RequestParam(name = "phonenumber", required = false) String phonenumber,
                     @RequestParam(name = "verifyCode", required = false) String verifyCode
) {
    log.info("start to send sms notification, reciever,host {},port {}, userName {} password {} destinations is {} verifyCode {}", host, port, userName, password, phonenumber, verifyCode);
    try {
        TCPIPConnection connection = new TCPIPConnection(host, Integer.parseInt(port));
        Session session = new Session(connection);
        BindRequest request = new BindTransmitter();
        request.setSystemId(userName);
        request.setPassword(password);
        //SMPP protocol version
        request.setInterfaceVersion((byte) 0x34);
        session.bind(request);
        String content = "[Registration]" + verifyCode + " is your verification code. Valid in 15 minutes. Please do not share this code with anyone else.";
        SubmitSM submitSM = constructRequest(phonenumber, content);
        SubmitSMResp response = session.submit(submitSM);
        String result = new String(response.toString());
        log.info("send sms notification result is {}", result);
    } catch (Exception e) {
        log.error("invoke sms session exception", e);
    }

}

private SubmitSM constructRequest(String phoneNumber,String content) throws WrongLengthOfStringException, UnsupportedEncodingException {
    String recipientPhoneNumber = phoneNumber;

    SubmitSM request = new SubmitSM();
    request.setDestAddr(createAddress(recipientPhoneNumber));
    request.setShortMessage(content,Data.ENC_UTF8);
    request.setReplaceIfPresentFlag((byte) 0);
    request.setEsmClass((byte) 0);
    request.setProtocolId((byte) 0);
    request.setPriorityFlag((byte) 0);
    request.setRegisteredDelivery((byte) 1);// we want delivery reports
    request.setDataCoding((byte) 0);
    request.setSmDefaultMsgId((byte) 0);
    return request;
}

private Address createAddress(String address) throws WrongLengthOfStringException {
    Address addressInst = new Address();
    // national ton
    addressInst.setTon((byte) 5);
    // numeric plan indicator
    addressInst.setNpi((byte) 0);
    addressInst.setAddress(address, Data.SM_ADDR_LEN);
    return addressInst;
}

这里是异常消息

我查看了openSMPP的源代码以了解原因，因为帐户绑定失败，sessoin将被关闭；执行session时会导致异常。
