Migration from Camunda 7.21 (JDK8) to Camunda 7.22 (JDK21) and Tomcat 10

We are migrating our application from Camunda 7.21 to 7.22 and from Java 8 to 
Java21 and Tomcat 10. On our shared Camunda server we have a deployment of a bpmn that uses 
several JavaDelegates to run different DMNs. We have switched the application to "JakartaServletProcessApplication" 
to come around this "javax/jakarta" problem but when we are executing "javaDelegate.getProcessEngine().getDecisionService()" 
we are retrieving a DecisionService which uses "javax.servlet.ServletContextListener"

Does anyone know what is going wrong and how I can fix it?
