"IllegalArgumentException: URI is not hierarchical" thrown for @WebService.wsdlLocation=file:path/MyService.wsdl

Related to JIRA XFIRE-481

When the @WebService.wsdlLocation identifies a wsdl on the file path, an Exception is thrown stating, in part, "IllegalArgumentException: URI is not hierarchical"

There are no imported documents in my WSDL, so the problem must be the URI of the wsdl file itself.

I'm attaching my WSDL.

Here's the stacktrace:
