Hi :
Trying to understand how JSSE and to debug a java 7 client ssl handshake
problem

What is specified in teh server's security certificate ?
I saw a field called Version ( X.509 version ). Does it mean that the
certificate decides the TLS version ?

Or is that negotiated during handshake ?


How can I force the client to specify TLSV1.2 during *ClientHello *?
