-----------------------------------
Summary: Reconsider the "avoid the expensive and useless stack
trace for api exceptions" practice
Key: KAFKA-7016
URL: https://issues.apache.org/jira/browse/KAFKA-7016
Project: Kafka
Issue Type: Bug
Reporter: Martin Vysny
I am trying to write a Kafka Consumer; upon running it only prints out:
{{ org.apache.kafka.common.errors.InvalidGroupIdException: The configured
groupId is invalid}}
Note that the stack trace is missing, so that I have no information which part
of my code is bad and need fixing; I also have no information which Kafka
Client method has been called. Upon closer examination I found this in
ApiException:
{{/* avoid the expensive and useless stack trace for api exceptions */}}
{{@Override}}
{{public Throwable fillInStackTrace() {}}
{{ return this;}}
{{}}}
I think it is a bad practice to hide all useful debugging info and trade it for
dubious performance gains. Exceptions are for exceptional code flow which are
allowed to be slow.
