Java EE (Java Enterprise Edition) General Discussion

So I started looking at JavaMail today and came up with this.

import java.util.Properties;
import java.security.Security;
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 MailClient
{
    private static final String[] recipient = {"********@gmail.com"};
    
    
    public static void main(String args[]) throws Exception
    {
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
 
        new MailClient().sendMessage(recipient, "Testing", "Testing123...", "*******@gmail.com");
    }
 
    public void sendMessage(String recipients[], String subject, String message, String from) throws MessagingException
    {
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.auth", "true");
        props.put("mail.debug", "true");
        props.put("mail.smtp.port", "465");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "false");
 
        Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator()
        {
            protected PasswordAuthentication getPasswordAuthentication()
            {
                return new PasswordAuthentication("********", "********");
            }
        });
 
        session.setDebug(true);
 
        Message msg = new MimeMessage(session);
        InternetAddress addressFrom = new InternetAddress(from);
        msg.setFrom(addressFrom);
 
        InternetAddress[] addressTo = new InternetAddress[recipients.length];
        for (int i = 0; i < recipients.length; i++)
        {
            addressTo[i] = new InternetAddress(recipients);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);

msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
}

It gives me the following debugging info and exception.
