             Summary: Java Null Pointer Exception when calling from JAXB Unmarshal Function
                 Key: XERCESJ-1638
                 URL: https://issues.apache.org/jira/browse/XERCESJ-1638
             Project: Xerces2-J
          Issue Type: Bug
          Components: JAXP (javax.xml.parsers), SAX
         Environment: Unix
            Reporter: saicharan poduri


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
