title: spring integration wire-tap and logging-channel-adapter logging issue
body: <p>I am trying to add wire-tap to intercept the channel but it is not using my logback configuration but instead it uses org.apache.commons.logging.impl.Jdk14Logger. 
    How do tell LoggingHandler.messageLogger to use lmy logback configuration?</p>
  
  <pre><code>&lt;int:channel id="testChannel"&gt;
      &lt;int:interceptors&gt;
          &lt;int:wire-tap channel="loggerChannel"/&gt;
      &lt;/int:interceptors&gt;
  &lt;/int:channel&gt;
  
  &lt;int:logging-channel-adapter id="loggerChannel" level="DEBUG"/&gt;
  </code></pre>
  
  <p>My logback has following configurayion defined</p>
  
  <pre><code>&lt;logger name="org.springframework" level="DEBUG"/&gt;
  &lt;logger name="org.springframework.integration" level="DEBUG"/&gt;
  &lt;logger name="org.springframework.integration.handler.LoggingHandler" level="DEBUG"/&gt;
  
  
  &lt;root level="DEBUG"&gt;
      &lt;appender-ref ref="STDOUT"/&gt;
      &lt;appender-ref ref="ROLLING"/&gt;
  &lt;/root&gt;
  </code></pre>
