SSLv2Hello HandshakeException

[Justvuur]

Hi there,

I'm using Java 1.8.241 with Embedded Jetty 9.29.
I've been using the AtmosphereClient to connect.

I've recently tried making changes to the server to make use of HTTPS but the client is unable to connect. I get a javax.net.ssl.SSLHandshakeException: SSLv2Hello is disabled error.
I've chatted to the Jetty guys, they say that SSLv2Hello has been disabled by default from Java 7+.

My question/issue, is it possible to use the AtmosphereClient with HTTPS?
Can it be configured to use TLSv1.2 or greater?
If so, do you have an example I could look at?

Thanks in advance!
