Chris, thanks for sharing this. I've recently ran across a similar tool:

http://www.bolet.org/TestSSLServer/

That does the same thing as your code but may be a little bit more elaborate. 
It also has a source code on link. Since you has shared your code, I might as 
well share this - the more the better.

George

Lots of things have been fixed/added in more recent versions of Tomcat 6.0.x. 
Please give a quick test against Tomcat 6.0.latest: you don't even need to 
deploy your own web application on it; just configure it for SSL and hit the 
default web application (the Tomcat documentation), or the examples, or 
whatever.

SSLLabs picks the ciphers it wants to check for; usually a group of "good" 
ciphers to make sure that you can support the latest-and-greatest ciphers, plus 
a bunch of them that are known to be broken (like most SSL-only ones).

This tool may help you test, because it's a whole lot faster than SSLLabs' 
tests:
