I don't know about the Tomcat 5.5.9 on JVM 1.7 but why not upgrade 
Tomcat as well? I couldn't find 5.5.9 in the archives, but 5.5.12 is 
from 2005-09-23 and 5.0.30 is from 2004-11-24 so I guess 5.5.9 is from 
somewhere in 2005 which is almost 8 years ago! O' boy that is out of 
date and has some serious security flaws.
