Answer 1

I have been getting the same error for long time.

When i changed session debug to true

Session session = Session.getDefaultInstance(props, new GMailAuthenticator("xxxxx@gmail.com", "xxxxx"));
session.setDebug(true);

I got help url https://support.google.com/mail/answer/78754 from console along with javax.mail.AuthenticationFailedException.

From the steps in the link, I followed each steps. When I changed my password with mix of letters, numbers, and symbols to be my surprise the email was generated without authentication exception.

Note: My old password was more less secure.
