The thing is that, when you use Java 17 there is file in webapps/geoserver/WEB-INF/lib called marlin-0.9.3.jar . Full path is webapps/geoserver/WEB-INF/lib called marlin-0.9.3.jar. Delete marlin-0.9.3.jar and your problem will be solved. More information you can find here https://docs.geoserver.org/latest/en/user/production/java.html#running-on-java-17
