The recent JDK 7 snapshot releases support TLS 1.2 (see 
http://download.java.net/jdk7/). You're able to get and run the very 
simple sample code for simple HTTPS connections from 
http://download.oracle.com/javase/7/docs/technotes/guides/security/jsse/JSSERefGuide.html#HTTPSSample.

If you run Java with "-Djavax.net.debug=all -Dhttps.protocols=TLSv1.2" 
options, you would be able to find the detailed debugging log for 
TLS/SSL handshaking.

About the detained tech guides, please refer to 
http://download.oracle.com/javase/7/docs/technotes/guides/security/jsse/JSSERefGuide.html.
