title: TLSv1.3 - is it available now in Java 8?
body: <p>Recently I noticed that some SMTP (mail) clients trying to connect to SMTP server by using STARTTLS command and specifying TLSv1.3 version during handshake.. Currently TLSv1.2 and a few other options is enabled. So, could it be that TLSv1.3 is available now? Or hackers again playing :)?</p>
