---------------------------------

             Summary: Throttled Replicas validator should validate that the 
proposed value is parseable
                 Key: KAFKA-12986
                 URL: https://issues.apache.org/jira/browse/KAFKA-12986
             Project: Kafka
          Issue Type: Bug
          Components: admin, core
            Reporter: David Mao


The ThrottledReplicaListValidator currently allows a string like 

leader.replication.throttled.replicas=,0:1 to be set

which is unparseable by the TopicConfig callback handler.

For robustness, the validator should also validate that the property can be 
parsed.
