TengYao Chi created KAFKA-18243: ----------------------------------- Summary: Loggers#loggers should not add rootLogger again. Key: KAFKA-18243 URL: https://issues.apache.org/jira/browse/KAFKA-18243 Project: Kafka Issue Type: Bug Reporter: TengYao Chi Assignee: TengYao Chi Fix For: 4.0.0
In log4j1, the {{LogManager#getCurrentLoggers}} method returns all loggers except for the root logger. Therefore, in the {{org.apache.kafka.connect.runtime.Loggers#loggers}} method, the root logger needs to be manually added back to the returned result. However, in the new log4j2, the {{getCurrentLoggers}} method no longer exists. Instead, the {{LoggerContext.getConfiguration().getLoggers()}} method is used, which returns all loggers, including the root logger. As a result, following the current logic in the {{org.apache.kafka.connect.runtime.Loggers#loggers}} method would result in a collection containing two root loggers. -- This message was sent by Atlassian Jira (v8.20.10#820010)
