DCT-Watermark.jar rev24 Seems to silently not watermark certain jpegs. #2

What steps will reproduce the problem?
1. download the attached file
2. run java -jar dct-watermark-rev24.jar e -d white.jpg offwhite.jpg "Hello 
Charlie"
3. examine offwhite.jpg (appears watermarked)
4. run java -jar dct-watermark-rev24 x -d offwhite.jpg 
5. an empty string is output, and error correction reports "0 bits of 96 are 
faulty" (I'm not sure that the error correction is relevant or not)

What is the expected output? What do you see instead?
I think I'd expect to see "Hello Charlie" on the output, or at least some 
indication of failure.

What version of the product are you using? On what operating system?
I'm using dct-watermark rev24, Ubuntu 12.04, linux 3.2.0-30-generic and OpenJDK 
Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
