For what it's worth, upgrading the JVM is usually painless (with a few
exceptions, but it's easy to try!).

Since you were already on Tomcat 5.5, the transition from 5.5 -> 7.0
(latest) is pretty much a drop-in replacement (you'll need to re-write
your server.xml from scratch, but it shouldn't be a big deal to
re-configure your <Connector>s).
