Question

Hi All,
I m trying to send Mails to multiple users with the MailerBackp.java. But it is trowing some exception in parsing the InternetAddress
import java.util.*;
import java.util.concurrent.*;
public class MailerBackup {
     private final FileCollection to;
     private static ArrayList<String> emails ;
     public MailerBackup(String addressFile){
          to = new FileCollection(addressFile);
          emails = new ArrayList<String>();
          //No of remaining emails.
          int remaining = to.size();
          System.out.println("Remaining is: "+remaining);
          int noOfmailAtATime = 500;
          int counter = remaining/noOfmailAtATime;
          System.out.println("Counter is == "+counter + "   no of Mails at a time =="+noOfmailAtATime);          
          String email= "";     
          int start = 0;
          int end  = 0;
          if(to.size()> noOfmailAtATime){
               end = noOfmailAtATime;
          }else{
               end = to.size();
          if(counter>=1){               
               for(int i=0; i<counter; i++) {     
                    System.out.println("i is : "+i);
                    System.out.println("Start is "+start+" and end is "+end);
                    for(int j=start; j<end; j++ ){
                         email = email + "," +to.get(j);     
                    start = end;                    
                    email = email.substring(1);
                    emails.add(email);
                    email = "";
                    if(i< counter-1){
                         end = end + noOfmailAtATime;     
          System.out.println("End is :"+end);          
          if(end < to.size()){
               int count = 0;
               System.out.println("Inside if");
               for(int i= end; i<to.size(); i++){
                    System.out.println();
                    email = email + "," +to.get(i);
                    count = i;     
               email = email.substring(1);               
               emails.add(email);
               email="";
               System.out.println("End is =="+count+" and to size is "+to.size());
    public static void main(String[] args) {
        try{
             BlockingQueue<Runnable> queue = new ArrayBlockingQueue<Runnable>(200);
             ThreadPoolExecutor executor = new ThreadPoolExecutor(50, 50, 1, TimeUnit.SECONDS, queue);
                if (args.length != 1) {
                     System.err.println("Usage: java ExecutorExample address_file" );
                     System.exit(1);
              MailerBackup mailer = new MailerBackup(args[0]);
              MailBean bean = null ;
              MailSender sender = null;
             long time = -System.currentTimeMillis();
             time += System.currentTimeMillis();              
//Here Emails is an ArrayCollection<String>, where each String consist of
//multiple comma seperated emails .
             for(int i = 0; i < emails.size(); i++){
                  bean = new MailBean();
                   bean.setSubject("Mail Bean Test");
                   bean.setMessage("Hi This is a Test Message, Please Ignore this Message");
                   System.out.println(emails.get(i));
                     bean.setTo(emails.get(i));
                     executor.execute(new MailSender(bean));
             System.out.println(time + "ms");
              System.out.println("Finished");          
        }catch(Exception ex){
             ex.printStackTrace();
}For sending Mails, My MailBeans send method is :
public Message createMessage(){
         try{              
              Message msg = new MimeMessage(session);
               msg.setFrom(InternetAddress.parse(FROM, false)[0]);
               msg.setHeader("X-Mailer", "VMailer");
               msg.setSentDate(new Date());
               if(getTo() != null || getTo() !="")
               msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(getTo(), false));
               if(getCc() != null || getCc() !="")
                    msg.setRecipients(Message.RecipientType.CC,InternetAddress.parse(getCc(), false));
               if(getBcc() != null || getBcc() !="")
                    msg.setRecipients(Message.RecipientType.BCC,InternetAddress.parse(getBcc(), false));
               msg.setSubject(getSubject());
               msg.setText(getMessage());
               return msg;                        
         }catch(Exception ex){
              ex.printStackTrace();
         return null;          
    public void sendMessage(){
         try{
              Message msg = createMessage();
              transport.send(msg, msg.getAllRecipients());
         }catch(Exception ex){
              ex.printStackTrace();
    }Error is while parsing the Mails.
