title: PowerMock will not work with JAXB Unmarshal
body: <p>I'm creating a test case wherein, I input xml and unmarshal it to procced with processing. I'm trying to use PowerMock and I keep getting</p>
  
  <pre><code>javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.xxxxxxx.org/xxxxx/xx/xx", local:"Element"). Expected elements are &lt;{}NotifRQ&gt;,&lt;{http://www.xxxxxxx.org/xxxxx/xx/xx}NotifRS&gt;,etc

  <p>I unmarshal it in this Fashion:</p>
  
  <pre><code>JAXBContext jaxbContext = JAXBContext.newInstance(NotifRQ.class);
          Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
          NotifRQ notifRQ= (NotifRQ) unmarshaller.unmarshal(new File("filename"));
