NPE when processing XMLStreamReader Midstream
---------------------------------------------

         Key: XMLBEANS-78
         URL: http://issues.apache.org/jira/browse/XMLBEANS-78
     Project: XMLBeans
        Type: Bug
    Versions: Version 2    
 Environment: Latest CVS, Windows XP, Java 1.5
    Reporter: Dan Diephouse
    Priority: Blocker


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:

java.lang.IllegalArgumentException: prefix cannot be "null" when creating a QName
	at javax.xml.namespace.QName.<init>(Unknown Source)
	at com.bea.xml.stream.MXParser.getName(MXParser.java:1432)

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:

java.lang.NullPointerException
	at org.apache.xmlbeans.impl.newstore2.Cur$CurLoadContext.finish(Cur.java:3032)

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.
