-----------------------------------------
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
