Remko Popma updated LOG4J2-784:
-------------------------------
Description:
Using slf4j binding.
VM options:
{{-DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector}}
Appender:
{code}
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%highlight{%p | %d{DEFAULT} | %t | %C{1}.%M(%L) | %m%n}{STYLE=Logback}"/>
</Console>
{code}
Log message:
DEBUG | 2014-08-18 19:05:13,795 | main | ?.() | HashSet: [A, B]
Log message without the VM option "Log4jContextSelector":

You need to specify {{includeLocation="true"}} to force the logger to take a snapshot of the stacktrace for every log message before passing it on to the background thread. (See [async loggers manual|http://logging.apache.org/log4j/2.x/manual/async.html#Location].)
For example:
{code}
<Loggers>
<Logger name="com.foo.Bar" level="trace" includeLocation="true">
<AppenderRef ref="Console"/>
</Logger>
<Root level="info" includeLocation="true">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
{code}
