- Ubuntu 20.04
- Temurin 17 JDK
- Apache Tomcat 9.0.65
- Jenkins LTS 2.346.2
Background
We used to run Jenkins on JDK 8 with Tomcat 8 until a plugin updated that contained Java 11 compiled classfiles. Instead of rolling back, decided to upgrade to JDK 17 and latest Tomcat 9 and updated to latest LTS version.
Problem
It somehow seems that if Jenkins is deployed when restarting Tomcat, the war actually shrinks in size from 90~ MB to 70 MB. Somehow losing class files in the process.
This causes some a lot of plugins to not load properly and hence the jobs fail to load aswell.
I can share logs/add debugging info, but I don't know which parts are relevant. Let me know if I need to share anything or check other things first!
