-------------------------------------
Summary: Kafka 3.8 no longer works on z/OS due to hard dependency
on zstd-jni
Key: KAFKA-17891
URL: https://issues.apache.org/jira/browse/KAFKA-17891
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 3.8.0
Environment: z/OS
Reporter: Dave Crighton
Kafka 3.8.0 has introduced a hard dependency on zstd-jni. This library at
runtime unpacks a native lib onto the system in a temporary location. Which in
itself is an insecure practice. It then attempts to load this library.
Unfortunately this fails on z/OS because zstd-jni does not include a library
for this platform and this therefore means we are unable to update to the Kafka
3.8 java client for IBM Integration Bus on z/OS.
Since the pre-req is only for optional compression it should be a soft
dependency and fail only when the functionality is actually used.
