IMAP空闲方法挂起+ javax.mail + groovy

Question

我已经配置了快递IMAP服务器并测试了IDLE功能，它在使用telnet时工作正常

  machinexxx:~$ telnet hostname 143
    Trying x.x.x.x...
    Connected to hostname.
    Escape character is '^]'.

当我从我的grails应用程序中尝试相同时，它只是挂在java邮件IMAPFolder idle（）命令上，并且没有得到任何更新。有什么想法吗？我试图搜索其他问题看起来没有直接的解决方案（他们建议多线程或创建一个线程来调用idle（）方法，然后重新运行相同的线程）有任何一个实现它请分享代码。谢谢！

  def serviceMethod() {


        log.info("Email Service check for emails!")

        runAsync {   
        Properties props = new Properties()           


        props.setProperty "mail.store.protocol", "imap"
        props.setProperty "mail.imap.host", "hostname"  
        props.setProperty "mail.imap.port", "143"

        def sess = Session.getDefaultInstance props, null      
        def store = sess.getStore "imap"        

        IMAPFolder inbox

        try{


              store.connect("hostname", 143, "loginname", "password") 

              inbox = store.getFolder "INBOX" 

              inbox.open(Folder.READ_WRITE)

              inbox.idle(false)

              def messages = inbox.search(new FlagTerm(new Flags(Flags.Flag.SEEN), false))

              def contents, bodyPart
                messages.each { msg ->

                println("${msg.subject} ${msg.sender}")

              }        
        } 
        catch(MessagingException e){
            log.error "Issue with connecting to email store or accessing folder or messages: " + e
        }
        catch(Exception eX){
