    Description

      I'm using Log4j version 2.1 and trying to use a Syslog appender to log to a syslog server (rsyslog). I'm using the configuration given at the official site (http://logging.apache.org/log4j/2.x/manual/appenders.html#SyslogAppender):

      <Syslog name="RFC5424" format="RFC5424" host="localhost" port="514"
              protocol="UDP" appName="MyApp" includeMDC="true"
              facility="LOCAL0" enterpriseNumber="18060" newLine="true"
              messageId="Audit" id="App"/>
      

      When I start my app and do a LogManager.getLogger(), I get an error:

      The same thing works on an older version of log4j 2.0-beta9.
