CXF versus Java builtins in 1.6

[Benson Margulies]

We've got some code that works fine with a JAX-WS client via wsdl2java
materials when run in isolation. Dropped into open office (don't ask), we
end up with an error and a non-CXF backtrace. Another JAR of ours included
in the classpath works fine. What possible pranks could OO be playing to
prevent CXF from setting up shop?
