Is javamail a less secure application?

Question

I was just working on an email program that read emails from Gmail and does further processing. Initially using the code provide in SO(link provided below) I was getting an exception which says that "My access has been blocked and I need to login via web browser".

On the same time I saw an email in inbox (to which I am trying to connect) which says that "Google Account: sign-in attempt blocked" and I need to disable modern security from following link "https://www.google.com/settings/security/lesssecureapps".

I tried to disable and I was succesfully connected.

So does it means that Javamail is a less secure application? Or there are ways by which I can still connect without disabling the option?

Thanks in advance. Garry

It's really hard to tell because Google isn't saying exactly what "modern security standards" an app needs to implement to be "more secure", but I suspect they're referring to this blog entry where they talk about OAuth2. JavaMail is capable of using the OAuth2 authentication mechanism, which I guess makes JavaMail a "more secure" application.
