IOException when parsing PDF files

[Godmar Back <go...@gmail.com>]

Hi,

on the off-chance any other Nutch users have seen this:

*This is a problem not with Nutch, but with PDFBox (both with 0.7.4 as well
as with the newer 0.8.0) - it can be reproduced by running their text
extractor from the command line.

Interestingly, Poppler (pdfinfo, pdftotext) groks the PDF just fine - is
there a Poppler-based PDF text extractor for Nutch, perhaps?
