I recently upgraded Linux mint 21.3 to 22 and it downgraded thousands of packages. I tried removing and reinstalling openjdk-21-jre since jstock was failing to load with this reflect error. I reinstalled v.11 and changed the launch script to:

JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

And I still get these errors but at least it runs! Hope this helps anyone having this problem:
