WSDL2Java with -allowElementReferences with cxf 2.2.x

[Shannon Hastings]

When in run wsdl to java on a wsdl doc using references in the message where
the message uses the same data type twice, ie to create a method that looks
like foo(Bar arg1, Bar arg2) I get the following error from wsdlToJava:

WSDLToJava Error: Element {http://org.cagrid.introduce/2/Services}Service
has Having the same name with different types[null -- null],  In wrapper
style, there is a collision as per the spec.

I do not get there error if I only have one ref of the Bar type.  Below is
the snippit of wsdl that causes this error (note: the element test uses the
introduce-ns0:Service  type twice which seems to be ok with spec and I would
expect it to create the method test(Service arg1, Service arg2) ).
