> Sequence of events
> 1) Task A starts in a container
> 2) Task A complete event comes to AM
> 3) Task B starts in the same container
> 4) Task A's input calls some method on its context. Crashes with NPE
> 5) The crash sends an input failed event for Task A to the AM
> 6) Task A state machine crashes saying cannot handle failed after success
> In some cases, it could be that status update event is also sent after completion, though not sure if its related to the failed event being sent.
