title: multiple log4j instance configuration
body: <p>I want to use multiple instances of the log4j Logger. I need to attach different Properties objects to each of these log4j Logger instances.</p>
  
  <p>Here is the code to configure for one instance:</p>
  
  <pre><code>LOG4J = org.apache.log4j.Logger.getLogger(Logger.class);
  
  Properties log4jProps = new Properties();
  
  ...
  
  PropertyConfigurator.configure(log4jProps);
  </code></pre>
  
  <p>What if I want to have two log4j instance and each of them has different properties?</p>
