</div></div>This error always implies that something went wrong with Bio-Formats'<br>
own TIFF reader - the vast majority of the time, it's something simple,<br>
and does not indicate that JAI is or should be required.<br>
<br>
Is there a stack trace prior to this in the log? Can you upload the<br>
file?<br>

</span>We've considered jai-imageio-core in the past; we haven't used it so far<br>
because it's not actively maintained, and the value added is minimal compared to<br>
the time required to add/test/maintain support for it. As far as I can see, it only<br>
buys us support for a couple of very uncommon TIFF codecs.<br>
<br>
If Douglas' file does indeed require support for one of those codecs,<br>
then we can certainly take a closer look at depending on<br>
jai-imageio-core, but I'd like to rule out an easier solution first.<br>
<br>
