James Perkins commented on WFLY-8942:
-------------------------------------
The problem seems to be the {{RequestScopeContext}} is destroyed before the injected bean
is used. My guess is since the HTTP request is complete, the context is destroyed. We may
need something similar to what is being done for EJB {{@RequestScope}}. Part of the EJB
implementation seems to be in Weld Core and the other part in WildFly.
[~mkouba] We may need your thoughts here. I'll attach a WAR which will easily
reproduce this issue. Currently batch creates the beans like
[this|https://github.com/wildfly/wildfly/blob/master/batch/extension-jbere...].
This creation part would happen before a new batch thread is launched. This is why I think
the bean has essentially fell out of scope because it lazily loads the injected
{{@RquestScope}} bean in a new thread.
Is there an easy way to handle this?
