--------------------------------------------------------------------
The (incorrect) image is being decoded as a result of ResourceValidationProcess
calling PDXObject.createXObject. This constructs a PDImageXObject, which
decodes the image stream. The decoding is needed because for some types of
images, some of the image information is taken from the image itself.
The problem is in page 3, it is /Img329 that doesn't decode.
This mentions a possible fix:

The updated source code is here:
https://java.net/nonav/projects/jai-core/sources/svn/content/tags/root-1_1_3/src/share/classes/com/sun/media/jai/codecimpl/TIFFFaxDecoder.java?rev=111
I haven't tested it. I don't really see this as a high priority unless it can
be proven that this is indeed a bug, i.e. that the image is correct.

The problem is in page 3, it is Img328 and/or Img329 that doesn't decode.
