> When the first entry in an array contains a null value, and that array is 
> used as the source for an <s:iterator> tag, a NullPointerException is thrown. 
> This exception did not occur in prior versions of Struts 6.x
> Exception:
>  
> {code:java}
> ERROR org.apache.struts2.dispatcher.DefaultDispatcherErrorHandler - Exception 
> occurred during processing request: null
> java.lang.NullPointerException: null

> org.apache.struts2.components.IteratorComponent.start(IteratorComponent.java:309)

> A trivial example would be this tag:
> {code:java}
> <s:iterator value="pages">
>     ...
> </s:iterator>{code}
> and Action:
>  
> {code:java}
> public class TestAction extends ActionSupport {    
>     private Object[] pages = null;    
>     
>     public String prompt() throws Exception {
>         pages = new Object[10];
>         return SUCCESS;
>     }
