I'm getting this random exception while looping through the Messages of my mailServer (is a hMailServer on local network):
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)
it happen while I for-loop the Message[] array from the server
The scope of (this part) of the Java program is pretty simple:
I've alredy tried this know fix: https://javaee.github.io/javamail/FAQ#imapserverbug (both the methods described)
the moveFromFolderTo() is where I apply the fix:
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;
the Message retrieved is the simplest for-loop:
Message messages[] = inboxFolder.getMessages();
but doesn't work, at random Message it crashes; the mailServer log doesn't help, at some point:
//for-loop start, Messages[] alredy fetched

javax.mail.MessagingException: Failed to load IMAP envelope

any help?
Made another test without the JavaMail-FAQ fix, looks like mailServer and clients are "out of synch":
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

but consider that from Thunderbird i can see only 4 email in my inbox

At least had to change mail server, i finally get it to work with Apache James; maybe a little more complicated than hMailServer but surly more stable.
