[cdi-dev] Contexts behavior in SE and Async Event for EDR1

[Martin Kouba]

I'm in favour of having the request context active during async event 
delivery. I.e. each notification will have it's own request context. The 
name of the context is not perfect but it would be consistent with other 
parts of the spec (@PostConstruct, EJB async, MDB, web service, ...). As 
I already said - HTTP-specific contexts should not be active during 
async delivery.

WRT @ThreadScoped - I don't think it's a good name. A better name would 
be @TaskScoped. We have a similar context in Weld SE but it needs some 
revision [1]. I'm not sure whether it would deserve to become/inspire a 
new built-in context though.
