Today I successfully got an async result from my local branch of Struts 
:) In this branch I did not change and keep Servlet 2.4 dependency but 
created a wrapper which invokes Servlet 3's API via reflection. Works as 
WW-4874's description.

That works but somehow is not awesome so I decided not pull requesting 
it now. I should do one thing before this. I discovered, currently, 
action invocation and result execution are hardly coupled in Struts. For 
example DefaultActionInvocation not only invokes action but also calls 
pre-result listeners and executes result!

So, at first, I will be working on separating coupled action invocation 
and result execution while keeping same functionality as before.

Then, after merge of above as a PR, if I could have robust 
implementation (e.g. timeout and etc listeners) via reflection, then I 
will PR against core, else against plugins.
