My code is 

package common;

import java.util.Date;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sun.mail.smtp.SMTPMessage;

public class SimpleMail{

    /**
           Outgoing Mail (SMTP) Server
           requires TLS or SSL: smtp.gmail.com (use authentication)
           Use Authentication: Yes
           Port for SSL: 465
         */
        public static void main(String[] args) {

             String to="mymailid@gmail.com";
             String subject="New Mail";

             String msg="test test";

            final String user="gmailuser";
            final String pass="gmailpassowd";
            Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.gmail.com");

            props.put("mail.smtp.auth", "true");

            Session session = Session.getInstance(props,new javax.mail.Authenticator() {

I have sent emails through the Gmail smtp in java using the Apache Commons Email library.
The documentation has a nice and simple example:

Email email = new SimpleEmail();
email.setHostName("smtp.googlemail.com");
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator("username", "password"));
email.setSSLOnConnect(true);
email.setFrom("user@gmail.com");
email.setSubject("TestMail");
email.setMsg("This is a test mail ... :-)");
email.addTo("foo@bar.com");
email.send();

Check your ports. From Google's support:

If you tried configuring your SMTP server on port 465 (with SSL) and port 587 (with TLS), but are still having trouble sending mail, try configuring your SMTP to use port 25 (with SSL).

Source: https://support.google.com/mail/answer/78775?hl=en

So, try using port 25 and see what happens.
