As mentioned in another post I have made a pull request on github to update the version of poi. I'm going to see if I can get the maintainer to allow me to merge it into the main repo.
I ran into the same issue so have made a pull request on the github repository with a version that seems to work with POI version 5.0 if that is of use to anyone. I'm going to see if I can get it merged into the main repo otherwise I might just publish it as a separate artifact.
