      Upon broker instance creation, following output is seen.

      SLF4J: Class path contains multiple SLF4J bindings.
      SLF4J: Found binding in [jar:file:/opt/amq-broker-7.2.0/lib/slf4j-jboss-logmanager-1.0.3.GA-redhat-2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
      SLF4J: Found binding in [jar:file:/opt/amq-broker-7.2.0/lib/slf4j-jboss-logmanager-1.0.4.GA.jar!/org/slf4j/impl/StaticLoggerBinder.class]
      SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
      SLF4J: Actual binding is of type [org.slf4j.impl.Slf4jLoggerFactory]
      done! Your system can make 7.58 writes per millisecond, your journal-buffer-timeout will be 132000
      
      You can now start the broker by executing:  
      
         "/opt/newbroker/bin/artemis" run
      
      Or you can run the broker in the background using:
      
         "/opt/newbroker/bin/artemis-service" start
      
      

      This 'slf4j' output (slightly different, but very similar problem ) was fixed in previous AMQ 7.1.0 release ( see linked issue, ENTMQBR-821 )

      This output ideally, should not be shown as part of broker instance creation ( first thing customer will see )
