Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 2.5.0
Reporter: Filippo Machi
Hello,
I am working on a java kafka stream application (v. 2.5.0) running on a
kubernetes cluster.
It´s a springboot application running with java 8.
With the last upgrade to version 2.5.0 I started to see into the logs some
NullPointerException that are happening when forwarding a record from a
punctuator.
This is the stacktrace of the exception
{code:java}
Caused by: org.apache.kafka.streams.errors.StreamsException: task [2_2] Abort
