Daniel Kulp commented on CXF-7159:
----------------------------------
I would consider this change to be just as invalid. You are adding types to a
namespace that already has a specific schema defined for it and isn't in your
control.
> Schema name conflict in collect when DTO class declares XmlType
> namespace=http://www.w3.org/2001/XMLSchema

> private java.lang.String parameters;

> Sources from WSDL:

> <wsdl:message name="SimpleFault">
> <wsdl:part name="parameters" type="xsd:string"></wsdl:part>
> </wsdl:message>
> ...
> <wsdl:fault name="Servicefault" message="tns:SimpleFault" />
> {quote}
> The offending Namespace http://www.w3.org/2001/XMLSchema is already added on
> schema collection instantiation and thus a conflict is determined as soon as
> the SimpleFault is hit on initialization.
> -I have devleoped a standalone test case you only need to extract and run
> "mvn test" for reproducing this. How can I upload it?-
