I know Tomcat can be flaky with redeployment and require restart at 
times, but that should be for the administrator to decide.

Also, it sounds like you are relying on Tomcat's automatic redeployment 
feature. If you manually undeploy the webapp, replace the files, and 
redeploy, there can be no risk of mixing up classes. Same if you deploy 
a WAR file - Tomcat will undeploy the old webapp before deploying the 
new one.

Replacing a running unpacked webapp without undeploying first is asking 
for trouble, of course.
