Subject [jira] [Created] (KAFKA-6180) AbstractConfig.getList() should never return null
Date Tue, 07 Nov 2017 11:18:01 GMT
Charly Molter created KAFKA-6180:

             Summary: AbstractConfig.getList() should never return null
                 Key: KAFKA-6180
                 URL: https://issues.apache.org/jira/browse/KAFKA-6180
             Project: Kafka
          Issue Type: Improvement
          Components: config
    Affects Versions: 1.0.0,,,,,
            Reporter: Charly Molter
            Priority: Trivial

AbstractConfig.getList returns null if the property is unset and there's no default.

This creates a lot of cases where we need to do null checks (and remember them).
It's good practice to just return an empty list as usually code naturally handles empty lists.
