             Summary: 2.0 much slower than 1.8 for certain PDF files
                 Key: PDFBOX-3503
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3503
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.2
         Environment: Windows 2012 R2, Oracle Java 1.8.0_91 64-bit
            Reporter: Andy McMullan


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.
