Hello,
I have recently converted some 2500 PDF files to text using PDFBox
1.7.0. While doing so, I ran into two problems on a minority of the PDF
files (some 5% are affected for each problem). Usually, I would now file
a bug and attach a sample PDF so that the problem can be reproduced.
However, the PDFs in question are not public, and I am not entitled to
publish them to the public. Is there any person who I could mail two
affected PDFs files, so that that person could nail down the actual bug
for a good bug description while keeping the actual files secret?
Either case, here is what I see. In all cases, the affected document can
be displayed with no problems in Adobe Reader.
Problem 1: The document is parsed to be empty (no pages), although it in
fact contains > 50 pages full of text. Running PDFDebugger on this
document produces this output (WARNUNG = WARNING):
17.07.2012 14:01:50 org.apache.pdfbox.pdfparser.XrefTrailerResolver
setStartxref
WARNUNG: Did not found XRef object at specified startxref position 116
Problem 2: On attempting to parse the document, I get an IOException.
PDFDebugger outputs the following on this document (SCHWERWIEGEND = SEVERE):
17.07.2012 14:01:10 org.apache.pdfbox.filter.FlateFilter decode
