#name_from_message ⇒ Object

Always use the original error message to retrieve the user input since JRuby 1.7 behaves differently from MRI/Rubinius.

class Name; end
error = (Name::DoesNotExist rescue $!)

# on MRI/Rubinius
error.name #=> :DoesNotExist

# on JRuby <= 1.7
error.name #=> :'Name::DoesNotExist'
