> In case "Rolling Filename Pattern" is not set by user and if the tailed file 
> is moved, then the new file will not be tailed.
> Besides, in such case, the processor will be endlessly triggered without 
> ingesting data: it creates a lot of tasks and consumes CPU. The reason is it 
> never goes in if statement L448.
> A solution is to look at size() and lastUpdated() of the tailed file to 
> detect a "rollover". However it won't allow the processor to ingest the 
> potential data added in the tailed file just before being moved.
