    [ https://issues.jboss.org/browse/WFLY-11116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13725815#comment-13725815 ]

-----------------------------------

Hi Paul

If I have the below code flow:

Method1{
    Method2();
    stm1;
}

Method2(){
     Method3();
      return;
}

Method3(){
       response.sendredirect("index.html");
}

When executing Method1 the below flow should be executed:
1-Execute Method2()
2-Execute Method3()
3-Execute Stm1
4-Execute response.sendredirect("index.html"); 

However Wildfly is executing as feollow.
1-Execute Method2()
2-Execute Method3()
3-Execute response.sendredirect("index.html") and in parallel execute stm1 

Kindly advice if there's any configuration settings to stop this behavior:

PS: Don't hesitate to contact me if you want further details.

Best Regards

> I have two Servlets Book and BookPreview the attribute is set in Book Servlet as follow:
>  
> Book.java
> TestBean testBean=null;
> if(session.getAttribute("testBean")!=null)
>      testBean = (TestBean)session.getAttribute("testBean");
> else{

>      session.setAttribute("testBean",testBean);
> }
> testBean.setAmount("10");
>  
> response.sendRedirect("BookPreview");
>  
>  
> The session attribute can be retrieved and the page is loaded normally and the Amount value is displayed however when submitting the form (Post Action in BookPreview.java) Null Pointer exception is generated.
>  
> BookPreview.java
>  
> TestBean testBean = (TestBean)session.getAttribute("testBean");
> String amount = testBean.getAmount; //Null pointer exception when submitting the form
>  
> <form method="Post" action="BookPreview">
