Description

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.
