it is not a vulnerability of Tomcat, nevertheless it can be fixed by it. 
You definitely _should_ fix it, since data integrity can not be assured on 
your https connections any more.

I have little to no Windows experienc; but my understanding is, that while 
running Tomcat on Windows Server, it will make use of the SSL/TLS 
libraries provided by Windows. Means: the Openssl solution will not work 
your your.
You would have to wait until MS provides a patch (some Windows guy should 
correct me on this if I'm mistaken).

Meanwhile you should investigate if you can fix it by clever choosing the 
Tomcat Connector; maybe some Windows- Tomcat Expert jumps on it :)

SSLv3/TLS man-in-middle vulnerability

The local IT Security team ran an HP "Web Inspect" and it showed a High
vulnerability for SSLv3/TLS known as CVE-2009-3555.
We are running JVM JRE 1.6.0._17 on the server.
You state on the site at end of
page that this is not a vulnerability depending on a number of factors.
This is very unclear tor us.
