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.
