比较方法违反了它的总契约！尝试向 Websphere mq 发送消息时

Question

我正在使用 spring jms 连接到 Websphere MQ。我正在尝试通过本地主机连接，现在不使用 jndi 信息。

Connection names (all as an example): hostname: <Websphere ip address> http://localhost:9043
given hostname 12.123.0.12

In Resources->JMS->Queue connection Factories
name: MQDemo
JNDI name: MQDemo

2 Queues:
name: MQ.T11.UPDATE.REQUEST
JNDI name: jms/MQ.T11.UPDATE.REQUEST

name: MQ.T11.INQUIRY.REPLY
JNDI name: jms/MQ.T11.UPDATE.REQUEST

DemoMain.java

在主要方法中：

ApplicationContext ctx = new ClassPathXmlApplicationContext("app-context.xml");
    // get bean from context
    JmsMessageSender jmsMessageSender = (JmsMessageSender)ctx.getBean("jmsMessageSender");
    // send to default destination 
         jmsMessageSender.send();

JMSMessageSender.java

package name: com.java.geek

 @Autowired
  private JmsTemplate jmsTemplate;


  /**
   * send text to default destination
   * @param text
   */
  @Cacheable("message")
  public void send() {
      System.out.println("in send");
        jmsTemplate.send(new MessageCreator() {
        @Override
        public Message createMessage(Session session)throws JMSException {

            System.out.println("in create message");
        Message message = (Message) session.createTextMessage("Hello JMS");
        return message;
        }
        });

    }

  public JmsTemplate getJmsTemplate()
  {
      return jmsTemplate;
  }

  public void setJmsTemplate(JmsTemplate jmsTemplate)
  {
      this.jmsTemplate = jmsTemplate;
  }

第

行

jmsTemplate.send(new MessageCreator() {

我无法连接到 Websphere MQ。请指出代码中的错误。

Answer 1

这看起来像是 MQ 缺陷，似乎与以下 APAR 匹配：

http://www-01.ibm.com/support/docview.wss?uid=swg1IC88187

说在 7.0.1.10+、7.1.0.3+ 和 7.5.0.1+ 中已修复（暗示未来的主要版本）。升级客户端以超过这些级别，问题应该得到解决。

Answer 2

这是 jdk 错误：http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7173464 您可以在虚拟机参数中附加 -Djava.util.Arrays.useLegacyMergeSort=true。
