> I'm using PDFBox 0.7.2. On a certain document
> (http://www-wds.worldbank.org/external/default/WDSContentServer/IW3P/IB/2005/12/27/000160016_20051227181308/Rendered/PDF/E12860v10P096469EAs.pdf),
> when I execute the following code:
> PDFParser pdfParser = new PDFParser( docStream );
> pdfParser.parse();
> PDDocument pdfDocument = pdfParser.getPDDocument();
> StringWriter textWriter = new StringWriter();
> PDFTextStripper textStripper = new PDFTextStripper();
> textStripper.writeText(pdfDocument, textWriter);
> I get the following nasty stack trace from deep inside
> PDFBox:
> Exception in thread "main" java.util.EmptyStackException
