Случайное «MessagingException: Не удалось загрузить конверт IMAP», проходящее через сообщения (ошибка почтового протокола IMAP сервера)

/ 28 июня 2019

Я получаю это случайное исключение при циклическом просмотре сообщений моего mailServer (это hMailServer в локальной сети): 

javax.mail.MessagingException: Failed to load IMAP envelope
    at com.sun.mail.imap.IMAPMessage.loadEnvelope(IMAPMessage.java:1532)
    at com.sun.mail.imap.IMAPMessage.getSubject(IMAPMessage.java:441)

это происходит, пока я зацикливаю массив Message[] с сервера

Область (этой части) Java-программы довольно проста:

  • Читать все сообщения из входящих сообщений
  • Читать тему
  • Переместить в нужную папку

Я уже попробовал это исправление: https://javaee.github.io/javamail/FAQ#imapserverbug (оба метода описаны)

moveFromFolderTo() - то, где я применяю исправление: 

public static Message moveFromFolderTo(Message mail, String sourceFolder, String DestinationFolder) {

        try {
    //this is the javaMailFAQ fix
            MimeMessage tmp = new MimeMessage((MimeMessage) mail);
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            tmp.writeTo(bos);
            bos.close();
            SharedByteArrayInputStream bis = new SharedByteArrayInputStream(bos.toByteArray());
            MimeMessage cmsg = new MimeMessage(session, bis);
    //this is the javaMailFAQ fix

            List<Message> tempList = new ArrayList<>();
            tempList.add(cmsg);
            Message[] tempMessageArray = tempList.toArray(new Message[tempList.size()]);

            Folder srcFolder = store.getFolder(sourceFolder);
            srcFolder.open(Folder.READ_WRITE);
            Folder destFolder = store.getFolder(DestinationFolder);
            destFolder.appendMessages(tempMessageArray);
            mail.setFlag(Flags.Flag.DELETED, true);
            srcFolder.close(true);

            return cmsg;

извлеченный Message - самый простой цикл for: 

Message messages[] = inboxFolder.getMessages();

но не работает, при случайном сообщении вылетает; Журнал mailServer не помогает, в какой-то момент: 

//for-loop start, Messages[] alredy fetched 
A8 FETCH 2 (ENVELOPE INTERNALDATE RFC822.SIZE)
A8 OK FETCH completed
javax.mail.MessagingException: Failed to load IMAP envelope
    at com.sun.mail.imap.IMAPMessage.loadEnvelope(IMAPMessage.java:1532)

любая помощь?

Сделан еще один тест без исправления JavaMail-FAQ, похоже, что mailServer и клиенты "не синхронизированы": 

Mails in folder: 6  //mails from getMessages.length
cycle-step : 1
mailSubject: test4

cycle-step : 2
mailSubject: test
moveToWorking ex:java.lang.IndexOutOfBoundsException: 2 > 1
moveToWorking ex:java.lang.NullPointerException

cycle-step : 3
mailSubject: test4
moveToWorking ex:java.lang.IndexOutOfBoundsException: 3 > 2
moveToWorking ex:java.lang.NullPointerException

cycle-step :4
//after some mail the usual Exception

    at com.horsa.antidatacap.main.Main.main(Main.java:31)

но учтите, что из Thunderbird я могу видеть только 4 письма в моем почтовом ящике

полный журнал отладки (session.setDebug(true);) для этого случая:

По крайней мере, пришлось сменить почтовый сервер, я наконец-то заставил его работать с Apache James;может быть немного сложнее, чем hMailServer, но значительно более стабильно.
