[cdi-dev] Concurrency Control

Hi all,

CDI spec does not define a common concurrency control mechanism. The time
any type of concurrency control is mentioned is in conjunction with EJB and
a rather restrictive one for conversation context.

CDI Spec:
The container ensures that a long-running conversation may be associated
with at most one request at a time, by blocking or rejecting concurrent
requests. If the container rejects a request, it must associate the request
with a new transient conversation and throw an exception of type

It would be helpful if a common configurable concurrency mechanism (EJB
Singleton style locking?) could be established for all normal scopes.

What are your thoughts on this?
