          Issue Type: Bug
          Components: Text extraction
    Affects Versions: 1.3.1

Hello and thanks for PDFBox.

We just started using PDFBox for text extraction(through Tika) 
and it fails to finish text extraction falling in an infinite loop
and never returning the text.

Please note that this happens only for a specific type of PDF
documents(used for hand writing recognition) such as the one attached. 
Not sure if this is a bug of PDFBox or due to the nature of the PDFs,
but I think that PDFBox should at least break out if extraction is not possible.

I wish I could give you more information but I know nothing about PDF format, 
parsing, etc. 
Please let me know if you need any information or my help in any way.

Thanks a lot for your time.
