Tilman Hausherr commented on PDFBOX-4872:
-----------------------------------------
It *will* be fixed in 2.0.21, I've included the target so we don't forget.
However the fix does not mean that you'll be able to view this file, it only
means that we avoid the ClassCastException. Maybe the file will be able to be
displayed / extracted, maybe not. I haven't committed the fix however I have an
idea what I'll do. Release will be in 3 - 4 months (probably).
