---------------------------------------

             Summary: Unable to configure Multiple triggering policies on 
rolling file appender using yaml configuration file
                 Key: LOG4J2-1100
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1100
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 2.3
            Reporter: Charles Leclerc
            Priority: Minor


I wanted to use yaml instead of XML for better lisibility of the configuration. 
Here is the configuration I am using :

{noformat}
Configuration:
  status: warn
  
  Appenders:
    Console:
      - name: Console
        target: SYSTEM_OUT
        PatternLayout:
          Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
    RollingFile:
      - name: File
        fileName: "${sys:user.home}/.btat/btat.log"
        filePattern: "${sys:user.home}/.btat/logs/btat-%d{yyyy-MM}-%i.log.gz"
        PatternLayout:
          Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
        Policies:
            - TimeBasedTriggeringPolicy:
                interval: 7
            - SizeBasedTriggeringPolicy:
                size: 100 MB
        DefaultRolloverStrategy:
          max: 20

  Loggers:
    Root:
      level: info
      AppenderRef:
        - ref: Console
        - ref: File
 {noformat}

When running the application I have the following error in the console (the 
file log doesn't work) :
{noformat}

{noformat}

I tried different changes but had no success. From what I understand the 
configuration above seems to be correct, but I may be wrong.
