I did further investigation,
I think this is a bug, I think this is a very scary
bug.

You dont need three iterators, I could reproduce this
very easily,

In your action class have the following,

 String[] testArray = new String[5];
             
             testArray[0]="test0";
             testArray[1]="test1";
             testArray[2]="test2";
             testArray[3]="test";
            
             
session.setAttribute("testArray",testArray);


 In your jsp have the following


<s:iterator value="#session.testArray" id="testarr">
  Value of the arry is
  <s:property value="#testarr"/>
  <br> 
 </s:iterator>


WHAT it prints is following Issue is for the 4th index
also it prints test, it should print empty

Value of the arry is test0
Value of the arry is test1
Value of the arry is test2
Value of the arry is test
Value of the arry is test 


This is a scary behaviour for me,

Has anyone reported this bug, Any JIRA issue raised.

Thanks
