The following test program reads image 0 and 1 from a given JPEG file.
Image 0 is read O.K., but the attempt to read the non-existent image at
index 1 fails with an IIOException from the underlying library. Instead,
the EOF condition should be detected and an IndexOutOfBoundsException
should be thrown.
