Error setting severity level to info

[dduugg]

I'm attempting to use the info severity level introduced in 1.9.0, but getting an error (apologies if I'm misunderstanding something).

---

Expected behavior

rubocop runs without error

Actual behavior

rubocop prints a stack trace

Steps to reproduce the problem

Create an empty file:

$ touch a.rb

Create the following .rubocop.yml file:

AllCops:
  NewCops: disable
Lint/EmptyFile:
  Severity: info

Then:

rubocop a.rb --only Lint/EmptyFile
Inspecting 1 file

Which formatter are you using?

[dduugg]

@dvandersluis how can one determine that?

Here's the output with the -d flag (apologies for omitting that in the bug report) and an explicit --format simple:

Thanks @dduugg I just wanted to check if you were explicitly using a formatter or not for more context. I'll look into this.
