TLS 2.1

Our contact is going to force us to going to use TLS 2.1 for futur communication.
on topic i found that this is depending from the JVM version you installed.
Now it seems we are using jre 1.7 at the moment on our windows system.
If I download a 1.8 version of JVM could I just copy the files into c:\mendelson\as2\jre?
Or do I need something else/more?

Kind regards,
