You need to destroy all of its temp and work files, wherever they live. Any unpacked content from the warfile, etc., it all needs to be destroyed between the restarts.

What's in the deployment descriptor used to tell Tomcat to load the IdP webapp? V2 being out of date notwithstanding, both versions have some documentation in the wiki around how to deploy the IdP to the container and what to put in idp.xml, and our instructions follow the approaches we suggest to use.

No. All of that content has to be destroyed if you restart the container. Thats' what's causing the problem, most likely.

Updating Tomcat or Java or both while its running will basically risk corrupting working files and leave a container that doesn't have a good reaction to that in a bad state. Tomcat is definitely one of those containers. It does not like things getting changed underneath it.

I think you already did. You did the upgrade under more controlled conditions, and it worked. Don't do it any other way, that's the point.
Even if your controlled test involved updating while it's running, that just means you got lucky that time. Do it again and you might not.
