Style/MethodName error on camel-cased class method

[matthewd]

0.34.2 (using Parser 2.2.2.6, running on ruby 2.2.2 x86_64-darwin14)

Style/MethodName doesn't seem to like:

class X
  def self.fooBar
  end
end

[bbatsov]

That's the expected behaviour. I'm not sure why do you think this is a problem. Could you elaborate?

[matthewd]

Sorry, this was indeed unclear. With autocorrect enabled, it errors:

An error occurred while Style/MethodName cop was inspecting ../x.rb.
undefined method `class_type?' for nil:NilClass

[bbatsov]

Hmm, I can't reproduce this.

Weird. It doesn't seem environment-specific for me... I'm not using any local config, and I just installed rubocop on a random box:

bravo:~% ruby -v
