Could not connect to SMTP host: smtp.gmail.com, port: 587;

Question

I can't seem to send email using java and was hoping you guys could help. Here's the code I'm using now (I've actually tried several examples and none of them work).

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

public class Mail {

    static Properties mailServerProperties;
    static Session getMailSession;
    static MimeMessage generateMailMessage;

    public static void main(String args[]) throws AddressException, MessagingException {
        generateAndSendEmail();
        System.out.println("\n\n ===> Your Java Program has just sent an Email successfully. Check your email..");
    }

    public static void generateAndSendEmail() throws AddressException, MessagingException {

//Step1     
        System.out.println("\n 1st ===> setup Mail Server Properties..");
        mailServerProperties = System.getProperties();
        mailServerProperties.put("mail.smtp.port", "587"); // TLS Port
        mailServerProperties.put("mail.smtp.auth", "true"); // Enable Authentication
        mailServerProperties.put("mail.smtp.starttls.enable", "true"); // Enable StartTLS
        System.out.println("Mail Server Properties have been setup successfully..");

//Step2     
        System.out.println("\n\n 2nd ===> get Mail Session..");
        getMailSession = Session.getDefaultInstance(mailServerProperties, null);
        generateMailMessage = new MimeMessage(getMailSession);
        generateMailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress("test@google.com"));
        generateMailMessage.addRecipient(Message.RecipientType.CC, new InternetAddress("test@google.com"));
        generateMailMessage.setSubject("Greetings from Crunchify.com..");
        String emailBody = "Test email by Crunchify.com JavaMail API example. " + "<br><br> Regards, <br>Crunchify Admin";
        generateMailMessage.setContent(emailBody, "text/html");
        System.out.println("Mail Session has been created successfully..");

//Step3     
        System.out.println("\n\n 3rd ===> Get Session and Send mail");
        Transport transport = getMailSession.getTransport("smtp");
        // Enter your correct gmail UserID and Password
        transport.connect("smtp.gmail.com", "***my google user name ****", "**** my google password *****");
        transport.sendMessage(generateMailMessage, generateMailMessage.getAllRecipients());
        transport.close();
    }
}

The error that I get from this is:

Exception in thread "main" javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587;

I'm successfully able to telnet into smtp.gmail.com 587 and get the response back 220 mx.google.com ESMTP k66sm21937006yhg.39 - gsmtp

The line of code that's having problem is: transport.connect("smtp.gmail.com", "my google user name *", "** my google password *");

I'm replacing my google user name * and ** my google password ** with my google login credentials. If anyone could help me figure this out I'd be just so happy as I've been trying to figure this out for hours.
