title: Why does the log show DEBUG?
body: <p>I've done the following configuration for akka </p>
  
  <pre><code>akka {
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    loglevel = "ERROR"
    logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
  }  
  </code></pre>
  
  <p>For me it means, show only <code>ERROR</code> logs, but it shows everything: </p>
