service jboss.undertow.deployment.default-server.default-host./v1: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./v1: Failed to start service

The EAR contains:
1.) An EJB JAR
2.) An WepApp WAR

The webapp uses JSF and JAX-RS.
None of our code seesm to be involved.

The EAR can succesfully deployet on an Weblogic AS.

When I start the WildFly AS with --debug mode and halt at BeanManagerProxy.getBeans() and directly continue the thread exectuion. the deployment of the EAR file works correctly. Feels like some race condition..

Any ideas how to fix this?
