             Summary: Fails to read most Sony A100 JPG files generated from Photoshop CS2

                 Key: IMAGING-97
                 URL: https://issues.apache.org/jira/browse/IMAGING-97
             Project: Commons Imaging
          Issue Type: Bug
          Components: Format: JPEG
    Affects Versions: 1.0
         Environment: Windows 7, JDK1.7, Imaging snapshot build from 20121013
            Reporter: William Saar
         Attachments: _DSC6099.jpg

This line fails with the exception at the bottom for most of my old JPG files shot with a
Sony A100, and sometimes processed by Photoshop CS2. I will attach a failing file.
BufferedImage img = Imaging.getBufferedImage(compressedThumbnailData, jpgDecodeParams);

where jpgDecodeParams are
ImagingConstants.BUFFERED_IMAGE_FACTORY, new RgbBufferedImageFactory()
ImagingConstants.PARAM_KEY_FORMAT, ImageFormat.IMAGE_FORMAT_JPEG

Exception:
org.apache.commons.imaging.ImageReadException: Invalid marker found in entropy data
