-------------------------------------------------------------
For your example:
Simply take any project, and stick the JSP-line
<s:property value="xxx == null ? 'Not yet determined' : xxx" />
into a JSP you can exercise from your browser.
(In the rare event an object with a getXxx() - Method exists on your value
stack,
you need to replace the xxx in this line with some obscure property that does
NOT exist.)
Exercise that JSP. If you see "Not yet determined" in your browser, you see the
bug.
If some "NoSuchMethodException" or similar gets thrown, the bug is no longer
present.
Does that help?

> Project: Struts 2
> Issue Type: Bug
> Components: Value Stack
> Affects Versions: 2.1.8
> Reporter: Andreas Krüger
> Assignee: Lukasz Lenart
> Fix For: 2.2.x
>
>
> Setup:
> struts.el.throwExceptionOnFailure=true in struts.properties
> In the value stack, there is no object which has any property "xxx"
> The JSP has <s:property value="xxx == null ? 'Not yet determined' : xxx" />
> Expected behaviour: As the property xxx is not defined, this should throw an
> exception.
> Behaviour seen: The string "Not yet determined" gets inserted into the HTML
> output as if nothing were wrong.
