title: Problem with log4j xml configuration
body: <p>i have little question, my log4j.xml configuration is listed below</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt;
  &lt;!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"&gt;
  
  &lt;log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"&gt;
      &lt;appender name="console" class="org.apache.log4j.ConsoleAppender"&gt;
          &lt;param name="Target" value="System.out" /&gt;
          &lt;layout class="org.apache.log4j.PatternLayout"&gt;
              &lt;param name="ConversionPattern" value="%-5p %c{1} - %m%n" /&gt;
          &lt;/layout&gt;
      &lt;/appender&gt;
       &lt;logger name="com.alsodeep"&gt;
          &lt;level value="info" /&gt;
          &lt;appender-ref ref="console" /&gt;
      &lt;/logger&gt;  
      &lt;logger name="org.springframework"&gt;
          &lt;level value="error" /&gt;
          &lt;appender-ref ref="console" /&gt;
      &lt;/logger&gt;
      &lt;root&gt;
          &lt;priority value="error" /&gt;
          &lt;appender-ref ref="console" /&gt;
      &lt;/root&gt;
  
  &lt;/log4j:configuration&gt;
  </code></pre>
  
  <p>and when i call a log.info("some info")  inside the com.alsodeep package it printed out twice, for example</p>
  
  <pre><code>INFO  AspectExample - Call it before method
  INFO  AspectExample - Call it before method
  Hello
  INFO  AspectExample - Call it after method
  INFO  AspectExample - Call it after method
  List content [[23, 243, 234, 23432]]
  INFO  App - final
  INFO  App - final
  </code></pre>
  
  <p>i'm confused with this, whats wrong with my log4j settings.</p>
  
  <p>PS when i remove appender from root element, everything is ok and my log info appear only once.</p>
