well, it doesn't sound like a gross problem- the insiginifcant
would be good suspects I guess.

Its hard to know if itext even thinks there is a problem.
I guesss a debug jar could help, I have gotten in to habit of using the
c++ preprocessor with java and can make build with various features
or for different target platforms ( even java is not entirely platform
independent).
Really this could be anything- an invalid input image, a messed up font, etc.
If you can identify what the reader is complaining about you should be able
to narrow down the possible code issues.
It is possible you could just dump the pdf as an ascii file and visually
compare the ascii to a known good one or see if the high bit is
now being reset using a binary dump utility etc.
