title: WARNING: Replicate resource: progressBox
body: <p>I am using ZK as a UI front and I am getting the following error on server startup:</p>
  
  <pre><code>WARNING: Replicate resource: progressBox
  Overwrite jar:file:/D:/app_servers/apache-tomcat-7.0.16x64/webapps/MyAPP/WEB-INF/lib/ProgressBox-4.0.jar!/metainfo/zk/lang-addon.xml
  </code></pre>
  
  <p>With the jar: <code>file:/D:/app_servers/apache-tomcat-7.0.16x64/webapps/MyAPP/WEB-INF/lib/ProgressBox-4.0.jar!/metainfo/zk/lang-addon.xml</code></p>
  
  <p>This error is repeated for almost all the custom components that is defined for the application. </p>
  
  <p>This error is expected if the jar existed in multiple locations but that is not the case and the error also points to the same jar. </p>
  
  <p>The only change that I have done is that I have added some jars which presents in a different location other than the WEB-INF\lib directory. </p>
  
  <p>What could cause such an error?</p>
