Thanks Romain! I'm trying to interpret it. There is no portable way to destroy a custom CDI context on session expiration. It's implementation specific whether CDI is up while session expires upon undeploy. - even session expiration upon node shutdown is implementation, and configuration specific in a distributed environment. Tomcat for example expires sessions locally on node, did not check others -
Best I can do: - introduce a flag ( for example a system property ) - observe @BeforeShutdown - from observer iterate through all active contexts, and destroy them. Or just skip it according to the flag. Am I understand it right? 2017-02-26 13:24 GMT+01:00 Romain Manni-Bucau <rmannibu...@gmail.com>: > Yes, depends the session manager impl there.
