Andy Seaborne commented on JENA-2193:
-------------------------------------
That is not a stacktrace in any useful sense.
A text stacktrace is something that IDE can use to navigate the code. Not an
image.
> XMLHandler#endElement can throw NPE

> Key: JENA-2193
> URL: https://issues.apache.org/jira/browse/JENA-2193
> Project: Apache Jena
> Issue Type: Improvement
> Reporter: Henry Kuijpers
> Priority: Major
> Attachments: screenshot-1.png

>
> In our case:
> {code:java}
> package org.apache.jena.rdfxml.xmlinput.impl;
> public class XMLHandler extends ... {
> public void endElement(String uri, String localName, String rawName)
> throws SAXException {
> this.frame.endElement();
> this.frame = this.frame.getParent();
> this.frame.afterChild();
> }
> }
> {code}
> The result of getParent was null, which triggered a NullPointerException.
> However, maybe the issue is one of the upper layers (I'm not too familiar
> with all the internals of JENA/RDF and I also don't see any nullability
> annotations)?
