Description

I have a situation where I have a WSDL with some XML as its service documentation. Also I do not have a default namespace declared. This means that the xml that I have within the documentation is not namespace qualified. Under this situation Woden throws an error when trying to parse the WSDL with the following exception. I've also attached a WSDL that causes this issue. Do we need a null check in DOMXMLElement that cheks this before creating an URI?

Caused by: java.lang.NullPointerException

Fixed NPE and changed WSDL520 error handling so that a null NS uri will not result in this error being reported.
