[jira] [Resolved] (XERCESJ-1638) Java Null Pointer Exception when
calling from JAXB Unmarshal Function
[ https://issues.apache.org/jira/browse/XERCESJ-1638?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Glavassevich resolved XERCESJ-1638.
-------------------------------------------
Resolution: Invalid
Classes in com.sun.xml.internal.* and com.sun.org.apache.xerces.internal.* packages are not part of Apache Xerces. You appear to be using Oracle's JAXP implementation. We do not contribute to or have any influence over that implementation.

> 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
> Labels: java, jaxb, nullpointerexception, xml

> 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
