> Any PDF which had wrong startxref was parsed with warning in PdfBox 1.8 thanks to self healing mechanism.
> In version 2.0 the COSParser.parseXref (called from PDFParser) tries to seek to the startxref position.
> If the position is wrong, but within the file size, the PDF is parsed with warning.
> But when the startxref is over the file size, the parsing ended with exception.
> We could either test if startxref is not over source.length(), or catch the exception.
