Major Description
I had asked about this on the cxf-users mailing list, and was told to enter it into JIRA:
-------
I am trying to generate Java code using CXF to work with a third-party tool which they provide as a web service. I have attached the WSDL for their service to this message. When I try to run the wsdl2java tool on it (using either CXF 2.0.5, which we've used before, and currently use for one other project, or with 2.2.3, which I downloaded when I started having problems), I get a NullPointerException with no useful error message:

There is no indication here as to what the problem is, and searching the web and the users@cxf archives, I don't find anything that seems related to this error.
When I try running with -validate to see if the WSDL is valid, it gives me the following error:

So it seems like there is an issue with conforming to the WS-I Basic Profile. However, I was under the impression that conforming to the BP was optional, and that a WSDL can still be valid even if it does not conform. I am sort of assuming that CXF is providing this message as informational, rather than as a requirement, but I don't know. Is it possible that this violation is what's causing the NullPointerException? And since this WSDL seems to be valid WSDL, even if it doesn't conform to the Basic Profile (it passes the validation at http://www.validwsdl.com/, for example), is there a way to get CXF not to require that it conform, and still generate Java client code? Since this is a third-party tool, we don't have the option of changing the WSDL or the service, so I'm hoping I can find a way to make this work.

I will attach a copy of the WSDL file we're using.
