[jira] [Created] (KAFKA-13032) Impossible stacktrace
Niclas Hedhman created KAFKA-13032:
--------------------------------------
Summary: Impossible stacktrace
Key: KAFKA-13032
URL: https://issues.apache.org/jira/browse/KAFKA-13032
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 2.8.0
Reporter: Niclas Hedhman
I am presented with a stacktrace that has not a single touch point in my code, so it is incredibly difficult to figure out where the problem could be.
I think more RuntimeExceptions need to be caught and pull out information at each level that is providing any additional hint of where we are.
```
org.apache.kafka.streams.errors.StreamsException: Exception caught in process. taskId=0_140, processor=KSTREAM-SOURCE-0000000000, topic=_poll, partition=140, offset=0, stacktrace=java.lang.NullPointerException
