> There could be a possible problem with the NiFi ListFile -> FetchFile
> combination when using variables that do not exist in the ListFile processor.
> Steps to reproduce:
> * configure the ListFile's input directory to some variable that does not
> exist ${foo}
> * connect the ListFile to FetchFile and configure FetchFile to delete files
> * start the processors
> * NiFi resolved the ${foo} to empty String or null (not sure) and starts to
> fetch files from the NiFi working directory
> * NiFi autodigests itself
