while obtaining the session use the following code (You use null)

 Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
 
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("gmailid", "password");
}
});
 
session.setDebug(debug);
 
Message msg = new MimeMessage(session); 

Also you may set the following in props

  Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);  //smtp.gmail.com
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", SMTP_PORT); //465
props.put("mail.smtp.socketFactory.port", SMTP_PORT); //465
props.put("mail.smtp.socketFactory.class", SSL_FACTORY); //I used javax.net.ssl.SSLSocketFactory
props.put("mail.smtp.socketFactory.fallback", "false");
