Description

I have a very large XML file (29GB) where every other alternate line is a XML. I am sending out the line to a unmarshaller which then creates java objects. I didn't face this problem when I tried my code on smaller files (~1GB).

while(headerline!=null) {
sCurrentLine = br.readLine();
idDetails = IDUnmarshal.IDUnmarshall(sCurrentLine);
idObjectList.add(idDetails);
headerline = br.readLine();
}

I am getting the following null pointer exception
