----------------------------------------
Summary: NullPointer in ProcessorParameters.toString
Key: KAFKA-14325
URL: https://issues.apache.org/jira/browse/KAFKA-14325
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 3.3.1
Reporter: Martin Hyldgaard
After switching from {{Transformer}} to using {{FixedKeyProcessor}} I get some
NullPointer exceptions logged. It seems to be due to
{{ProcessorParameters::toString}} using it's field {{processorSupplier}}
without a null check. After KAFKA-13654: Extend KStream process with new
Processor API ([#11993|https://github.com/apache/kafka/pull/11993]) this field
can be null and instead the field {{fixedKeyProcessorSupplier}} is set.
