Same issue while trying to upgrade to JDK18 - is there a simple workaround available or a plan to get this wonderful library to work with JDK18? Thanks

For now you can use -Djava.security.manager=allow but on longer run it would need majore rework - https://openjdk.java.net/jeps/411

Bumped into same error when upgrading to jdk 21

I am only using ExpectedSystemExit from system-rules. If there is alternative to this, please let me know!
