Hi Matthias,
Here's the repro of the project that has these issues
https://github.com/zveljkovic/kafka-repro.
Please look at the:
Topology definition:
https://github.com/zveljkovic/kafka-repro/blob/master/src/main/java/com/example/demo/DemoApplication.java
FixedKeyProcessor:
https://github.com/zveljkovic/kafka-repro/blob/master/src/main/java/com/example/demo/MyFixedKeyProcessor.java
Test of FixedKeyProcessor:
https://github.com/zveljkovic/kafka-repro/blob/master/src/test/java/com/example/demo/MyFixedKeyProcessorTest.java
Test is where I am having issues.
Thanks,
Zed

Not sure right now, but could be a bug.
Can you maybe share the full stack trace and the test program?
