Tilman Hausherr commented on PDFBOX-2976:
-----------------------------------------
Yes... Of the two java competition products, one is able to display the file,
the other one isn't. The PDFTools PDF/A-1b validator mentions "Error in Flate
stream: data error. (6)". GS is able to display the file. PDFBox 1.8 brings
also an error, but is able to display the file at the second access in
PDFReader. Same for rev 1633496 of the 2.0 version. Maybe there's an incomplete
decoded stream and it isn't deleted. (Stream handling was changed recently)
I wonder if that incorrectly configured web server did other evil things to
these poor PDF files, which might go away after the correction.
