When trying to deploy MicroProfile Reactive Messaging Quickstart (https://github.com/wildfly/quickstart/tree/main/microprofile-reactive-messaging-kafka) using XP4 image and S2I method, the deployment fails due to  java.lang.NoClassDefFoundError: org/reactivestreams/Publisher. This is an issue for users, that want to use features of MP RM 2.0 in their applications, as we are marking this API to be provided by the server.
