>                 URL: https://issues.apache.org/jira/browse/LOG4J2-1573
>             Project: Log4j 2
>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 2.7
>            Reporter: Steffen Offermann
>            Priority: Minor
>
> This configuration used to work in 2.6.2:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="warn" packages="com.aixigo.tec.logging">
>    <Appenders>
>       <Console name="myConsole" target="SYSTEM_OUT"/>
>       <Async name="myConsoleAsync">
>          <AppenderRef ref="myConsole" />
>       </Async>
>    </Appenders>
>    <Loggers>
>       <AsyncRoot level="info" />
>    </Loggers>
> </Configuration>
> {code}
> With the current {{master}} (i.e. the upcoming 2.7) this does not work any more. The validator complains because the field "layout" is missing in
> {code:xml}
>  <Console name="myConsole" target="SYSTEM_OUT" />
> {code}
> According to the current documentation this is a bug:
> ||Parameter Name||Type||	Description||
> | layout | Layout | The Layout to use to format the LogEvent. If no layout is supplied the default pattern layout of "%m%n" will be used.
> With this configuration it works:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="warn" packages="com.aixigo.tec.logging">
>    <Appenders>
>       <Console name="myConsole" target="SYSTEM_OUT">
>          <DetailsLayout/>
>       </Console>
>       <Async name="myConsoleAsync">
>          <AppenderRef ref="myConsole" />
>       </Async>
>    </Appenders>
>    <Loggers>
>       <AsyncRoot level="info" />
>    </Loggers>
> </Configuration>
> {code}
