ECA listens to exceptions and dispatches the EcaExceptionEvent event so that models can do something in that scenario. However, if such a model throws an exception itself, that's currently just exiting with that exception and Drupal's exception handling is taken out of the loop.
Instead, the ECA exception listener needs to add the exception as the throwable to the original event and return back to the kernel which will handle the rest.
