title: Intermittent java.lang.IndexOutOfBoundsException at javax.faces.component.AttachedObjectListHolder.restoreState
body: <p>I have a JSF 2.1.21 application with client state saving method. I'm also using PrimeFaces 3.5 + Tomcat 7.0.37. </p>
  
  <p>I use OmniFaces full ajax exception handler to display a custom error page and email me with the stacktrace when a problem happens. </p>
  
  <p>Every day I get at least one email with a java.lang.IndexOutOfBoundsException. It seems to be related with redeployment of the application, but I'm not able to reproduce it.</p>
  
  <p>Here is the stacktrace:</p>
  
  <pre><code>java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
