Why wrong tracker? (was Re: [jira] Commented: (COMDEV-4) External
entity in XML causing null pointer exception during DocumentBuilder.parse)
I wonder why we are getting so many of these. I've only ever seen one
or two incorrectly classified issues on projects. Is there something
about the name of our tracker that makes people think it's the right
place?
