"stats-util -m" NPE after adding new IPs to /config/spiders

[Anthony Petryk]

Hello,

We're trying to add remove spiders from our Solr stats by adding offending IPs to a file in [dspace]/config/spiders then running "dspace stats-util -m".  However this results in the following NullPointerException:

How can we resolve this? 

Thanks,
