Hello, Commons Configuration is tested with Java 8, 11 and 17: https://github.com/apache/commons-configuration/blob/master/.github/workflows/maven.yml
What happens when you run on Java 11? This kind of error can happens when you compile a on Java 9 and run on Java 8. Did you recompile Configuration yourself or are you using it as a Maveb dependency?
