Getting a very similar error trying to upgrade to to Tomcat 11 on Java 21 to upgrade to xwiki 17.1.0.
On Windows, the space after "add-opens" needs to be an equal sign. I have all those JVM flags set. Still getting the error.
Here is my stack: {code:java} 2025-03-31 12:55:30,778 [main] ERROR h.i.DefaultExtensionJobHistory - Failed to read extension job history from [C:\ProgramData\xwiki\extension\history\2024.11.25.xml].
