Hi,
Thanks, fixed in https://issues.apache.org/jira/browse/PDFBOX-5577
I wonder if there will be further problems. Please test with a snapshot
version in a few hours:

Hi,
Below is a bug I discovered in pdfbox (2.0.27, Windows, JRE 1.8.0_361). I
traced it through the code and saw there is in fact a way that a (probably
malformed) form could generate the NPE. I wish I could share the pdf document
to reproduce, but I cannot. Perhaps looking at the where a null could come
from in acroFormLegacyMode will clarify the situation. It's pretty clear when
you look at the relevant code.
I think there should be a null check, and then skip the problematic field if
you find one... or at least emit a more helpful message.
Thanks,
Chris
