You have it right.
This is going to be hard enough for HTTP request but at least the Servlet container is
fully in control of the underlying connection so determining when a request ends can be
reliably detected. It's much harder for MDB, WebSocket, etc with async involved in
possibly many Java EE APIs (but it's not impossible).
That being said, just getting it working correctly for HTTP request is a huge step
forward.

For me a request is anything which comes into the context of the application. No matter
if it comes in via Servlet, WebSockets, JMS, Remote EJB, etc...
The request scope should be propagated to all asynchronous operations launched within
that call, terminating it when all request associated asynchronous operations are
completed.

This passes CDI TCK but for the particular request scope I would be happy to clarify it is
actually bound to the request and just reuse the same instances. In term of side effects
it would breaks the current thread safety users assume (with reason or not) but I have no

this is precisely the sort of thing that the EE concurrency spec is intended for. It is
supposed to copy over everything from the underlying thread local context into the new

managed, it also applies to CDI beans as well. The EE vendor is supposed to make sure this

I wanted/would like. CDI TCK breaks it quite easily and @RequestScoped which is *used*
today is sadly a @ThreadLocalScoped badly named. So to solve it we would need another
scope as I mentionned several times on this list 100% matching servlet instances
lifecycles (on a pure CDI side we have the same issue for sessions which are recycled
during a request, the session scope is corrupted *by spec* in term of user behavior).

concurrency- utility can't be reliable for "EE" users, 2. CDI still prevent

another thread (

in concurrency-utilities for EE at least. That was the first impl I did then Mark pointed
out it was violating CDI spec and request scope definition. There is a kind of
contracdiction there cause concurrency-utilities doesn't integrate with CDI at all but
we can also see it the opposite way: CDI doesn't provide any way to propagate a
context in another thread. Both point of view are valid so we need to see where we tackle
it.
