Tilman Hausherr commented on PDFBOX-2935:
-----------------------------------------
Thanks. I tried to render that file with the pre-fix version, there's a warning
and a default font is used. For 1.8, an NPE would be thrown. So I've added a
fix we have in the 2.0 version to avoid the NPE in 1.8 as well. The NPE in 1.8
strengthens my opinion that this PDF feature is not used in the wild.
