Hotmail SMTP not working with javamail

I am trying to write a simple Java program to send emails from my hotmail account using JavaMail API. Here is my code :

import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class HotMailSend {
public static void main(String args[])
{
    final String username = HOTMAIL.username;
    final String password = HOTMAIL.password;

    Properties props = new Properties();
    props.setProperty("mail.smtp.auth", "true");
    props.setProperty("mail.smtp.starttls.enable", "true");
    props.setProperty("mail.smtp.host", "smtp.live.com");
    props.setProperty("mail.smtp.port", "587");

    Session session = Session.getInstance(props,
      new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
      });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(HOTMAIL.username));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(GMAIL.username));
        message.setSubject("Testing Subject");
        message.setText("Hey Buddy..!!!,"
            + "\n\n No spam to my email, please!");

        Transport.send(message);

        System.out.println("Done");

    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
}

}

And here is the error I am getting :

I've used SMTP/Javamail with Hotmail before, so it definitely works. Were you sending a lot of emails in a short time? (I think they may block your mail or send it to the junk folder when you do that as a spam prevention measure.)
