> The code leading up to the call to extract text is as follows:

> parser.parse();
> pdDocument = parser.getPDDocument();
> setContent(new PDFTextStripper().getText(pdDocument));
> I hope the formatting is ok! Have you encountered this error before and can

> Ben,
> I just ran the PDF through our text extraction test -- without error.
> I'm not sure what to say about the error you've encountered.
> I do find that since version 0.73 came out Ben has updated the FlateFilter
> source code.  Have you tried the latest code or just the 0.73 build?

> Hi again, sorry, but your 13/05 and 14/05 nightly build jar and zips seem
> to be corrupt. Maven can't use the maven jars, and WinRAR throws an error
> while opening all of them, zips and jars.
> Am I doing something wrong, or are they corrupt?

> Hi again. I've just checked back for a response, and as there isn't any,
> have gone to try the nightly builds again. However there don't seem to be
> any! I'm trying http://www.pdfbox.org/dist - have they moved? I really want

> I don't see nightly builds ... I'll see if I can find out about those.

> Thanks Daniel - I came across the new site myself, but, you're right, I
> couldn't see any nightly builds. If you could let me know what the plan is,
> that'd be great, otherwise I'll check back next week.
> Thanks for your help,
