Java Null Pointer Exception when calling from JAXB Unmarshal Function

    Details

      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
