Yes, you are right. I just checked servlet 3.0 final and this is what's
written :
*A.1 Changes since Servlet 3.0 Proposed Final*
*1. Re-factored some of the Async APIs - moved addAsyncListener to
AsyncContext and renamed it to addListener. Moved setAsyncTimeout to
AsyncContext and renamed it to setTimeout.*

You bring another point by mentioning XA transactions. If we take the
transaction service out of the EJBs and make it available to managed beans,
would that mean that managed bean will then be able to do XA transactions ?
