> Hi
> I was investigating a failure to parse and debugging the pdfbox code when I noticed in the PDF document that I can't forward at the end of the file this:
> %%EOF^M
> ^M
> ^M
> <script type="text/javascript">^M
> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");^M
> document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));^M
> </script>^M
> <script type="text/javascript">^M
> try {^M
> var pageTracker = _gat._getTracker("UA-7429935-1");^M
> pageTracker._trackPageview();^M
> } catch(err) {}</script>^M
> ^M
> ^M
> So the document ends.. but there is more content.. basically some javascript. What the parser does is it gets to 
> line 492 in org.apache.pdfbox.pdfparser.PDFParser
> isEndOfFile get's set to true, but because it's not the end of the actual stream.. it continues this was a fix in PDFBOX-979.
> Next time around in the loop it reads
> <script type="text/javascript">
> which I think it ignores.. then trys to read 
> var
> twice as a number. Then blows up.. so I've playing around thinking of sensible thing to do. But worried that I might introduce some other issue. I assume this is legal structure for a PDFDocument. It opens fine in a viewer.
