The problem occurs if an only if CXF jars are placed under
$CATALINA_HOME/endorsed.This was a mistake on my part as I w under the
impression that $CATALINA_HOME/lib should remain pristine. Turns out the
endorsed directory is used to override classes delivered by the JDK itself.
Placing CXF libraries under $CATALINA_HOME/lib (for all applications) or at
WEB-INF/lib (per application) makes it work.
The patch was simple. Check is getClass().getClassLoader() returned null, if so
then use the context ClassLoader itself.

I haven't seen any issues in running CXF in Tomcat 8, we've had it added
to the actual war, looks like you put CXF into the common lib folder ?
If yes, how did you patch it for the given resource be loaded if it is
'null', did you delegate to the system loader ?
Thanks, Sergey
