I use Java 17 with Jetty 11.0.9. I started Jetty with the following command
java --add-opens=java.base/java.lang=ALL-UNNAMED -jar start.jar
Then I am facing exception followings.

I have confirmed that it works fine in a non-servlet standalone.
Does the --add-opens parameter work correctly in a servlet environment?
Or could it be due to other causes such as javassist?
The unit test does indeed succeed. It does not fail all the way on Jetty either, it seems to be processed correctly up to the halfway point. It also looks like the error occurs when running multiple runs in a thread.
--list-config is followings.
$ java -jar start.jar --list-config
