Looking for PDF with JPX streams

I'm currently working on a patch for poppler that makes use of OpenJPEG to decode JPX streams instead of the xpdf inherited code because the inherited code does not work for some PDF and i think that there's no reason not to use an already existing solution if it works. And that's the question, i need more PDF with JPX streams to be sure my 170 lines of code + OpenJPEG can replace the 3200 of xpdf code without any regression.

So if you could

cd /
find -name "*pdf" -exec grep -H JPXDecode {} \;

or as said in the comments

locate -0 .pdf | xargs -0 -n 1 grep -H JPXDecode

and send me (aacid@kde.org) a link to the pdf or the file pdf itself of all the files that match.
