> For handleInputInitializerEvent - this should be fairly straightfoward to handle. At
the moment this is an inline call from within the AsyncDispatcher, and will end up causing
a RuntimeException. The RuntimeException can be changed to a AMUserCodeException which will
take care of this.
> For onVertexStateUpdated, this eventually gets invoked from within RootInputInitializerManager.
Catching exceptions there and sending a RootInputInitialzierFailedEvent should be enough to
fix this ? May require some state machine changes to handle this event on a few more states.
