      Weld SE container 0e65e92d-f825-4f57-a229-d860e5ef04f2 shut down by shutdown hook

      I started a cdi container. And press ctrl c to stop. And this error is thrown.

          Hi Seto,

          it looks like the DefaultShutdownCallbackRegistry (Log4j) attempts to register a Log4j-specific shutdown hook per a new logger instance (used by Weld, org.jboss.weld.logging.ContextLogger). But since this happens during a JVM shutdown, specifically during a Weld shutdown hook execution (Weld attempts to destroy all contexts correctly), DefaultShutdownCallbackRegistry throws IllegalStateException. This should not happen if you obtain any bean instance in your app - in this case, the logger should be initialized before the shutdown hook. If you don't use any bean in your app I think you can safely ignore this exception (no bean instance = empty contexts = no risk of incorrecly destroyed bean instances).

            What does it mean by obtain any bean instance? Of course there're managed beans in the app. It's with Java SE.

            This error is thrown when I use ctrl c to shutdown the app. Instead of normal main thread ended.

              What does it mean by obtain any bean instance?

              Do you get a bean instance and invoke a method upon it before stopping the app? I understand that you're using CTRL + C to shutdown the app - that's where a JVM shutdown hook gets into the game.

                The code is in the Kernel.java. And observes the ContainerInitialized event. And there's logic running in it.

                  Ok, what's the Kernel class? Is the source code available? I can see the DeltaSpike code there as well. Do you really need to switch between CDI implementations? If not, I would recommend to get rid of DS ContextController and stick with Weld API (e.g. starting application context is completely unnecessary because in Weld it's always active).

                    No. It's not available. But I'll try if I can make a minimum reproduce project.

                    The basic logic in my Kernel is starting Deltaspike CDI container and inject Infinispan Cache and use Distributed Executor Service to run some tasks.

                    But if I remember correctly, the exception will be thrown even without Infinispan logic.

                      A simple reproducer would be great!
