The root cause of the problem was related to some code we have that will try various tiff headers on the data stream before decoding it with JAI. The specific problem in this case is that the incorrect header information decodes without error and we get a garbled image.
The CCITTFaxDecoder was added a few versions ago that does a really nice job at decoding Tiffs. I've reworked the stream object logic to try CCITTFaxDecoder first and then only on a failure fall back to JAI.

The previously mentioned code changes are pretty high risk for regression. I have to run the change through QA. With a little luck there won't be any regressions and I won't have to reopen this issue.

There is a temporary work around in which if JAI is removed from the class path all will be good for this PDF. Working on a better solution going forward.
