extract_text goes on forever.

I installed latest PDFBox on my Mac via pip. 
I did an import and called on to the extract_text(<file>) method. And it keeps running perpetually for a 196 KB file. 
Please help. 

```
>>> import pdfbox as p, os
>>> os.path.exists(f).  # f is the file path
True
>>> pp = p.PDFBox()
>>> pp.extract_text(f)


```
extract_text(f) doesn't end, runs perpetually.
