Gary Gregory commented on LOG4J2-1573: -------------------------------------- I am pretty sure this has nothing to do with the builder because {{org.apache.logging.log4j.core.appender.ConsoleAppender.Builder.build()}} calls {{getOrCreateLayout()}} and I get the default pattern layout with this config file. This has to do with the async'ness of the set up... This works: {code:xml} <AsyncRoot level="info"> <AppenderRef ref="myConsole" /> </AsyncRoot> {code} This does not: {code:xml} <AsyncRoot level="info"> </AsyncRoot> {code} > Layout is no longer optional > ---------------------------- > > Key: LOG4J2-1573 > 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"> > <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.
