Gary Lucas commented on IMAGING-97:
-----------------------------------
I just entered Issue-368 describing problems I've seen with the file
_DSC6099.jpg that was contributed to Imaging's JUnit test suite following on
this Jira item. The image reader doesn't crash, but it fails to properly
decode the image. If anyone has suggestions, I might have time to look at
this.
