Surprisingly, some files with LZW errors do display with AR without an error
message. Either AR keeps quiet about it, or there is still a bug in the LZW
decoder. Both could be possible, AR doesn't show every error, and the PDFBox
LZW decoder is

> Fix For: 1.7

>
> Given the regressions we identified in PDFBox 1.8.7, we should upgrade to
> 1.8.8 as soon as it is ready. I'm tempted to call this a blocker on Tika
> 1.7. Let's use this issue to carry on the discussion of regression testing
> (if any further discussion is necessary) or any other prep that needs to
> happen before 1.8.8's release.
