Hi,

When we call Document.getPageCount() just after loading certain documents we’re getting a java.lang.NullPointerException. I will attach an example document here.

nullpointerexample.docx (13.7 KB)

Environment
We’re using v21.4 and I can reproduce this on Mac and on Linux.

JVM
openjdk 11.0.11 2021-04-20
OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9 (build 11.0.11+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+9 (build 11.0.11+9, mixed mode)

Stack trace:
