> When a ResourceProvider goes away while being activated, we remove it from the list of handlers for a given path. However, we don't remove the empty list of handlers in the case where it was the only available handler for a given path. 
> That can lead to a problem later on where we assume that if we have a list of handlers for a path it will at least contain one handler (and just use .get(0)). This happens in the ResourceProviderTracker.setObservationReporterGenerator method and will cause IOOB Exceptions from that point onwards.
