-------------------------------------
Summary: NullPointerException in shutdown following
InvalidConfigurationException
Key: KAFKA-18758
URL: https://issues.apache.org/jira/browse/KAFKA-18758
Project: Kafka
Issue Type: Bug
Components: core
Reporter: Edoardo Comar
A NullPointerException is thrown when the server is shutting down because of a
conflict topic config setting
{color:#0000ff}log.cleaner.max.compaction.lag.ms{color}{color:#000000}=5000{color}
{color:#0000ff}log.cleaner.min.compaction.lag.ms{color}{color:#000000}=10000{color}
Shutdown should happen without NPE polluting the logs:
