Sturts 2 - execAndWait...

I have a Struts2 application that has an action that can take anywhere between 1 sec to 5 mins to run. So, I'm using the execAndWait interceptor to display a wait page if the action takes more than 20 secs to run. The setup of the action looks like this:

    <action name="myAction" class="myActionClass">
    <interceptor-ref name="defaultStack" />
    <interceptor-ref name="execAndWait">
       <param name="delay">20000</param>
    </interceptor-ref>
    <result name="success">myPage.jsp</result>

    <result name="wait">waitPage.jsp</result>
    </action>

I have tested this with a scenario where the action just takes 1 second to run. I expected that the wait page will never be shown.

However, the wait page still showed up. I tried debugging my action class and method and found that the execution hangs at this statement below for the time specified in the <param name="delay">

In this case, it waits for 20 secs at the statement below and then completes execution successfully.
getSession().put(A_SESSION_VARIABLE, 10);

Note: MyActionClass does implement SessionAware

Has anyone else experienced this problem?  Is there a work around for this?

Thanks
