Javamail problem with SEEN flags (Autmatically updates the server)

Question

Hi all,
I am using Javamail 1.4.
When I read a message I used to get "java.io.IOException: No content" exceptions. Then I have created new MimeMessage from folder.getMessage() return as below
1) MimeMessage m = (MimeMessage)foldergetMessage(i);
2) MimeMessage mimeMsg = new MimeMessage(m);
After doing this I am seeing all my unread mails are shown as read in my server (thru' server's web access).
This is happening with step 2) only. If I comment out step 2, i will be getting others errors like, No content/BODY STRUCTRUE etc..
Am I doing anything wrong here?

Hi,
This is my client which reads the mail. I am using EmailArchitect as mail server.
I had few mails unread before executing this piece of code. But after when I saw the messages in server, they are shown as read.
package com.imap.client;
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.search.*;
import javax.activation.*;
public class ReadMail {
    public static void main(String[] args) throws IOException {
        getMessages();
        //getMessages();
     private static void getMessages() throws IOException {
          // SUBSTITUTE YOUR ISP's POP3 SERVER HERE!!!
        String host = "mail.com";
        // SUBSTITUTE YOUR USERNAME AND PASSWORD TO ACCESS E-MAIL HERE!!!
        String user = "[email protected]";
        String password = "password";
        // SUBSTITUTE YOUR SUBJECT SUBSTRING TO SEARCH HERE!!!
        String subjectSubstringToSearch = "Test E-Mail through Java";
        // Get a session.  Use a blank Properties object.
        Session session = Session.getInstance(new Properties());
        try {
            // Get a Store object
            Store store = session.getStore("imap");
            store.connect(host, user, password);
            // Get "INBOX"
            Folder fldr = store.getFolder("INBOX");
            Folder defFldr = store.getDefaultFolder();
            fldr = defFldr.getFolder("INBOX");
            fldr.open(Folder.READ_ONLY);
            int count = fldr.getMessageCount();
            System.out.println(count  + " total messages");
            // Message numebers start at 1
            for(int i = 1; i <= count; i++) {
          // Get  a message by its sequence number
                //Message m = (MimeMessage)fldr.getMessage(i);
                 MimeMessage m = (MimeMessage)fldr.getMessage(i);
                MimeMessage mimeMsg = new MimeMessage(m);
            // "true" actually deletes flagged messages from folder
            fldr.close(true);
            store.close();
        catch (MessagingException mex) {
            // Prints all nested (chained) exceptions as well
            mex.printStackTrace();
} //End of classThanks,
