      Description

      I tried to update my project from Jackrabbit 1.4 to 1.5 and found following error, that is critical for my app.
      Project uses Import/Export features of JCR and JAXB to map XML from JCR to java objects.

      exportDocumentView() works with streams when I call it like this:

      Unmarshaller umr = getUnmarshaller();
      ...
      fo = new FileOutputStream("/tmp/export-node.xml");
      jcrs.exportDocumentView(path,fo , false, false);
      fi = new FileInputStream("/tmp/export-node.xml");
      umr.unmarshal(new InputSource(fi));

      But it does not work when I call it using SAX event handler:

      UnmarshallerHandler ctxh = umr.getUnmarshallerHandler();
      jcrs.exportDocumentView(path, ctxh, false, false);

      giving following exception:

      Version 1.4. works fine.
