Hi, You're doing great work on this. I hope you come up with additional findings.
The guideline remains to use in-memory reloading judiciously in production applications. Frequently the time to restart Tomcat with a new version of the app is only marginally more than the time to reload the app in memory, and the former is significantly cleaner from the JVM's perspective.
