After upgrading my app to 1.1.6, I noticed that /rails/info/properties results in the error:
Recognition failed for “/rails/info/properties”
However in a new 1.1.6 app, the same route works fine.
Turns out, if 1.1.6 is present in vendor/rails, this route doesn’t work. If I rename vendor/rails to something else so vendor rails can’t be found, it starts working again.
Any reason for this behaviour? Is this a bug?
