Apache POI 3.14 was released in 2016 - 
https://poi.apache.org/devel/history/changes-3x.html#3.14

The fact that a version that is almost 7 years old, and predates Java 17 
by almost as long, doesn't work perfectly isn't a huge surprise. You need 
to use a more modern release

The latest Apache POI release is 5.2.3, you should try that. There are a 
lot of bug fixes in the last 7 years, see https://poi.apache.org/changes.html 
for a summary of the recent ones
