["Ralph Goers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-2341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16797673#comment-16797673 ] 

Ralph Goers commented on LOG4J2-2341:
-------------------------------------

This fix needs to be re-evaluated as it is causing a huge performance hit in the FlumeAppender when using the JSON Layout.

> In version 2.11.0 appenders with JsonLayout don't output json when Log4jContextSelector is set to org.apache.logging.log4j.core.async.AsyncLoggerContextSelector.
> Here is a sample:
> {code:java}
> package ru.yandex.zen;
> import org.apache.log4j.Logger;
> public class LoggerSample {
>     public static void main(String[] args) {
>         Logger logger = Logger.getLogger("LoggerSample");
>         logger.info("Message 1");
>         logger.info("Message 2");
>     }
> }
> {code}
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="WARN">
>     <Appenders>
>         <RandomAccessFile name="RandomAccessFile" fileName="async.log" immediateFlush="false" append="false">
>             <JsonLayout/>
>         </RandomAccessFile>
>     </Appenders>
>     <Loggers>
>         <Root level="info">
>             <AppenderRef ref="RandomAccessFile"/>
>         </Root>
>     </Loggers>
> </Configuration>
> {code}
> Without AsyncLoggerContextSelector the log looks like this:
> {code:java}
> ""
> ""
> {code}
> Without AsyncLoggerContextSelector:
> {code:java}
> {
> "thread" : "main",
> "level" : "INFO",
> "loggerName" : "LoggerSample",
> "message" : "Message 1",
> "endOfBatch" : false,
> "loggerFqcn" : "org.apache.log4j.Category",
> "instant" : {
> "epochSecond" : 1527061940,
> "nanoOfSecond" : 637000000
> },
> "threadId" : 1,
> "threadPriority" : 5
> }
> {
> "thread" : "main",
> "level" : "INFO",
> "loggerName" : "LoggerSample",
> "message" : "Message 2",
> "endOfBatch" : false,
> "loggerFqcn" : "org.apache.log4j.Category",

> },
> "threadId" : 1,
> "threadPriority" : 5
> }
> {code}
> In our main application Json logger outputs the provided message in quotes, not just an empty string. The problem doesn't appear when using asyncRoot or asyncLogger.
