I got the below exception in apache-cxf-3.1.2 and tried a lot to resolve it and did not get any positive help, So planned and upgraded to the latest version
Looks like you have WS-Discovery turned on. This is done by placing cxf-services-ws-discovery-service and cxf-services-ws-discovery-api in the classpath. Remove these from your classpath (e.g. from maven pom.xml) and you should no longer see the error messages.
