Well, I did the grep for you.   It's coming from WSS4J, not CXF, in: 
src/org/apache/ws/security/message/token/UsernameToken.java

Most likely, you DON'T want to setup the WSS4JOutInterceptor on the server 
side to have a UserNameToken.  That's not normally a usual occurrence.   (why 
would the server be sending BACK a Username?)
