Investigate JMH jar issue with Shadow 9.x #4096
Description
When we updated to Shadow 9.x our JMH testing pipeline stopped working, because the main class is missing in the JAR

Error: Could not find or load main class org.openjdk.jmh.Main

This is a major breaking change version of Shadow, so multiple things may have changed. Let's investigate before updating to Shadow 9.x.
