Bug in Sanselan.getImageInfo(File) with certain JPEGs causing java.lang.OutOfMemoryError or
java.lang.NegativeArraySizeException
--------------------------------------------------------------------------------------------------------------------------------

                 Key: SANSELAN-53
                 URL: https://issues.apache.org/jira/browse/SANSELAN-53
             Project: Commons Sanselan
          Issue Type: Bug
    Affects Versions: 0.94-incubator
         Environment: Windows, Unix
Sun Java JVM (multiple versions)
            Reporter: Dominic Early


In order to extract JPEG image dimensions, Apache Commons Sanselan (0.97) was used as follows:

  File imgfile = new File("./test.jpg");
  org.apache.sanselan.Sanselan.getImageInfo(imgfile);

For most JPEG images, this code works as expected.  However with specific JPEG files, the
call to getImageInfo() causes a repeatable java.lang.OutOfMemoryError or java.lang.NegativeArraySizeException
- depending upon the input JPEG file.  The same files can be processed with javax.imageio.ImageReader
without such issues.

The OutOfMemoryError is especially serious as it may cause JVM to fail.
