Jersey not happy with kotlin 1.2.10

I have a web backend running jetty/jersey. When I compile it with kotlin 1.1.61, it runs without issues. If I switch kotlin to 1.2.10, I get the following error:

14:31:36 WARN Could not send response error 500: javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: kotlin/reflect/KotlinReflectionInternalError

Could you please advise?

EDIT: Nevermind, upgrading jackson fixed the issue.
