Infinite Loop when parse XML File to Flat Flie. Bug SpringBatch or Not - xml-parsing

Question

I tried to parse an xml file to flatefile. All worked fine except at the end. In debug Mode the cause of the infinite loop is due to the method moveCursorToNextFragment( reader) in org.springframework.batch.item.xml.StaxEventItemRe ader.class.
More precisily in this part of method
while (reader.peek() != null && !reader.peek().isStartElement()) {
reader.nextEvent();
}
it seems that these conditions are not sufficient to recognize the end of the document.
I replace this part of code by this code to be sure the end of the document test
while (reader.peek() != null && !reader.peek().isStartElement() && !reader.peek().isEndDocument()) {
reader.nextEvent();
}
if (reader.peek() == null || reader.peek().isEndDocument()) {
return false;
}
below my context file and the link for an INSEE xmlfile : http://lei-france.insee.fr/Telechargement.do
I always taked the full file.
Here is my context file
