I tried out this tutorial to get my first tryout for OpenAPI contract-first development. I got the following error:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.1.RELEASE:run (default-cli) on project todo: An exception occurred while running. null: InvocationTargetException: Cannot load configuration class: com.redhat.todo.OpenAPI2SpringBoot: ExceptionInInitializerError: java.lang.reflect.InaccessibleObjectException-->Unable to make protected final java.lang.Class

And also here is the OpenAPI2SPringBoot.java mentioned in the error message:

I think due to other posts on the internet this might be a version problem, but I can't figure it out myself. Is someone here who can help me out?
