Brian Leathem commented on SEAMFACES-96:
----------------------------------------
Dan in IRC:
if it's the shudown event, try to get the BeanManager (there is a method to
safetly check) and if it's not there, then just skip it.
So rather than disabling the listener during the shutdown event, we'll just
filter the the events bridged to the CDI event bus, excluding those that during
the shutdown sequence, when the Bean Manager is not available.

> The offending line 25 in AbstractListener (extends BeanManagerAware) calls
> getBeanManager(). It seems that the BeanManager is not available during
> application shutdown.
> JSF publishes the event javax.faces.event.PreDestroyApplicationEvent
> So AbstractListener (or perhaps DelegatingSystemEventListener) could listen
> for this event, and disable itself to avoid throwing this error.
