David Handermann commented on NIFI-9527:
----------------------------------------
I was not able to reproduce this issue on Azul Zulu Java 11.0.12 running on
macOS 12.2 with the current main branch of NiFi 1.16.0-SNAPSHOT.
However, running under Java 17.0.2 throws a similar exception on startup.

The error is certainly related an older version of snappy-java 1.0.5 packaged
in {{{}nifi-hive-nar{}}}. [Version
1.1.7.3|https://github.com/xerial/snappy-java/blob/master/Milestone.md]
introduced support for Java 9 modules. Version 1.1.7.6 set the minimum Java
version 8, but there do not appear to be any other notable changes.
Upgrading module references to a newer version of snappy-java looks like an
improvement to address multiple issues.
