----------------------------------
Summary: org.apache.kafka.clients.admin.Config has broken equals
and hashCode method.
Key: KAFKA-6727
URL: https://issues.apache.org/jira/browse/KAFKA-6727
Project: Kafka
Issue Type: Improvement
Components: clients, tools
Affects Versions: 1.1.0
Reporter: Andy Coates
Assignee: Andy Coates
`Config` makes use of `Collections.unmodifiableCollection` to wrap the supplied
entries to make it immutable. Unfortunately, this breaks `hashCode` and
`equals`.
>From Java docs:
> The returned collection does _not_ pass the hashCode and equals operations
>through to the backing collection, but relies on {{Object}}'s {{equals}} and
>{{hashCode}} methods.
See:
