> SimpleSubscriptionManager's publish message catches exceptions but consumes them after logging them. This way at runtime, the actual publisher of the message, typically another capability in the resource, never knows that the publish failed.
> We can build a java listener based mechanism so that when a capability tries to call the publish operation, it must provide a reference to itself and implement a listener interface. This means we overload the publish method. If such a callback reference is available, the SimpleSubscriptionManager will call it back when it receives a fault, with the fault.
