   I've encountered this bug when running a client that has a transitive dependency on `org.apache.bookkeeper::circe-checksum` and built with Gradle. When run in a Docker container that has a base image of openjdk:11 or openjdk:17, I get the same `NoClassDefFoundError: com/scurrilous/circe/checksum/Crc32cIntChecksum` failure.
   
   I experimented with changing the packaging in the POM to `jar`, installing the library in my local m2 repo, and rebuilding my client app. When the transitive dep is a jar, the class loader finds `Crc32cIntChecksum` and I get the fall back message:
   
   > `WARN  com.scurrilous.circe.checksum.Crc32cIntChecksum - Failed to load Circe JNI library. Falling back to Java based CRC32c provider`
   
   The Gradle build is creating a fat jar for my client app. If it includes `circe-checksum` as a `.nar`, then the class loader doesn't find the class when running in the container, but it does when the build includes `circe-checksum` as a `.jar`.
   
   For reasons I cannot explain, when running my client app with Gradle `run` on macOS, I get the fall back message with the `.nar`.
