Re: What is this issue with java.util.zip.CRC32C?

I had a project like this. You should probably build with a more stable 
Java (LTS), and closer to your project's target Java. So probably JDK 
LTS. So for example JDK11:
https://adoptium.net/temurin/releases/?os=any&arch=any&version=11

So in short I wouldn't build with Java that comes with NB.

Cheers,
Maciej Nux
