Tim Allison commented on TIKA-1548:
-----------------------------------
I'll fix our PDFParser to stop any processing if decryption is unsuccessful.
This will prevent the logging errors among other things.
I was able to replicate the issue with pure PDFBox 1.8.8 on rhel, but not with
PDFBox-1.8-branch.

> I'm using Tika 1.7. I'm parsing an encrypted PDF document which raise an
