Unable to read PDF with embedded Black-And-White TIFF.

  Hello colleagues.

  Since a month or two I've started using PDF Box to read PDF files
received from a scanner. Recently some of the users started receiving
this error:

> java.lang.RuntimeException: EOL encountered in black run.
>  at org.apache.pdfbox.filter.TIFFFaxDecoder.decodeNextScanline(TIFFFaxDecoder.java:677)

  Opening the same file with evince yields:

  But the file still displays and the image content is visible.

  The files that exhibit this problem have sensitive information, and
I don't feel comfortable sharing those.
  However if anyone of the developers needs a sample I can probably
provide one off-list.

  Please advise.

There are some known issues concerning the CCITT filter. Most likely yours is
related to them.

Send it to me and I'll have a look to check if my assumption is correct or not.
