Re: [cdi-dev] @ThreadScoped?

In Resin we added it precisely for these reasons and because it is very useful for framework development as opposed to the Java SE thread local API. We started it whenever a thread starts and destroyed it when the thread ends just like thread local. It keeps things simple and consistent.

Background: @RequestScoped is often used as a ThreadLocal instance solution. A lot of SE or Batch implementations rely on it from what I saw as well as async implementations reusing existing business logic with this thread safety constraint. Proposal: providing a @ThreadScoped implementation is cheap for CDI and implemenation and would avoid the headache we can have with @RequestScoped. Will also remove the quite dark side of the spec regarding servlet request and request scope since now we would have a more natural solution for all of these situation so @RequestScoped goals wouldn't collide as much. Questions: - is it automatically started as request scoped is (JMS, @Async, ...)? Alternative could be some configuration in beans.xml (merged accross the app): <beans> <scopes> <thread> <active>JMS</active> <active>ASYNCHONOUS</active> </thread> </scopes> </beans> - start/stop API (this is typically an API the user should be able to control for its own threads) - CDI 2.*0*? wdyt?
