Jen Huang commented on PDFBOX-2266:
-----------------------------------
Wait why was this closed? The NPE gets thrown after the document is loaded.
Shouldn't it at least check for not null and skip (like the previous version
does) instead of erroring out?

> I have a pdf that throws an NPE in version 2.0.0 when rendering a specific
> page to an image. I've tested the pdf with 1.8.6 and it worked correctly.
> It logged a warning (java.io.IOException: Error: Unknown shading type 0) but
> did not throw any exceptions. I will attach the pdf. Let me know if you
> need any more info.
