Xavier Léauté updated KAFKA-4856:
---------------------------------
Description:
Calling KafkaProducer.close() from multiple threads simultaneously may cause
the following harmless error message to be logged. There appears to be a
race-condition in AppInfoParser.unregisterAppInfo that we don't guard against.
