> This problem is reported by Rick Bullotta:
> We're now have a test case that will always throw an NPE. And it is a
> VERY interesting and odd bug...here's the basics:
> 1) When used inside of the <redirect:write> element, a call to
> document() (or something it calls) throws an NPE...how here's the
> strange part...
> 2) ONLY WHEN the document being included has one or more attributes on
> its top level element!!!
> 3) If you use the following examples, anything referencing
> TestInput1.xml will work fine, whereas TestInput2.xml will fail!
> File: TestInput1.xml
> <?xml version="1.0" encoding="UTF-8"?>
> <Root>
> <Child>
> <SubChild>AAA</SubChild>
> <SubChild>BBB</SubChild>
> </Child>
