-------------------------------------

             Summary: MultiThread race condition in DefaultShutdownStrategy for suspend/resume
                 Key: CAMEL-11179
                 URL: https://issues.apache.org/jira/browse/CAMEL-11179
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.18.3
            Reporter: Benjamin Graf


If call to suspend with timeout does timeout than two threads are invoking forced processing
one for suspending and one for hard stopping. This causes the Consumer to be possibly left
in a dead state.

E.g. Jms consuming route:
1.) Timeout occurs, ShutdownTask gets completed before main thread
-> JmsConsumer gets stopped (listener gets destroyed), resume has no effect
2.) Timeout occurs, ShutdownTask get completet after main thread
-> JmsConsumer gets stopped first (listener gets destroyed) and get suspended second, resume
sets Consumer to started but the listener is still destroyed!
