> It is possible under some environments to receive an Exception that is
> not extended with Blamable (e.g. JRuby).
> ActiveSupport::Dependencies::Loadable#load_dependency blindly call
> blame_file! on the exception which throws it's own NoMethodError
> exception and hides the original Exception.

> This commit fixes #9521
