> While testing Tika 1.13 we've hit a performance problem with PDF conversion to text for certain files from the GovDocs corpus.
> I have attached an example PDF that shows the problem.  The problem can be reproduced using pdxbox-app.jar.  Running the extraction with 1.8.12 takes around 1 second:
> java -jar pdfbox-app-1.8.12.jar ExtractText 074031.pdf 074031.pdf.txt
> Doing the same with 2.0.2 takes around 30 seconds:
> java -jar pdfbox-app-2.0.2.jar ExtractText 074031.pdf 074031.pdf.txt
> This is a small PDF so taking 30 seconds seems excessive.
