From Jira WFLY-451:
Detect Apache CXF libraries in user deployment and if the webservices subsystem is actually being triggered for the deployment, either log a major warning or make the deployment fail. This would basically prevent later issues with users trying to deploy not properly packaged applications (e.g. the same war embedding CXF they were using on Tomcat) and making them aware of what they need to do.
Upstream fails the deployment, but the backport will only print a warning for the first CXF jar found.
deployment failure would be better, hope warning in the log will be noticed.
Verified on EAP 6.4.0 DR11
10:02:46,474 WARN [org.jboss.as.webservices] (MSC service thread 1-6) JBAS015599: Apache CXF library(ies) (cxf-rt-bindings-xml-2.7.13.redhat-4.jar) detected in ws endpoint deployment; either provide a proper deployment replacing embedded libraries with container module dependencies or disable the webservices subsystem for the current deployment adding a proper jboss-deployment-structure.xml descriptor to it. The former approach is recommended, as the latter approach causes most of the webservices Java EE and any JBossWS specific functionality to be disabled.
I'm also stuck on the same, did you get any solution?
