By using the plugin

       
           org.apache.cxf
           cxf-codegen-plugin

SOLUTION:
To exclude the dom4j dependency!

mvn dependency:tree > tree.txt

To find where dom4j comes.

Exclude the dependency:

     
        found_dependency
        found_dependency
        test
        
           
              dom4j
              dom4j
           
        
     

And fuck off the "pull-parser".
Add it to the exclusions.
