Upon reflection, this might be because it is continuing on all the way to the end of the document, regardless of where it starts. Can someone with more expertise than I comment on that?

> I am attempting to read in a SOAP response into XmlBeans with an XMLStreamReader. I've skipped to body in the XMLStreamReader. When doing a XmlObject.Factory.parse( streamReader ) it throws this:

> This is fixed easily enough, by checking if the prefix is null in the Locale class and acting accordingly. Once this is done though, I get:

> I'll attach a testcase showing this bug and my patch for Locale which checks for a null prefix. The null prefix bug could also be problem with the StAX RI - however I'ved tried it with both the RI and Woodstox. Both give me the same issue with the prefix being null.
