[1.9] Attempt to invoke any method on Delegator leads to ClassCastException
---------------------------------------------------------------------------
Key: JRUBY-4871
URL: http://jira.codehaus.org/browse/JRUBY-4871
Project: JRuby
Issue Type: Bug
Components: Ruby 1.9, RubySpec, Standard Library
Reporter: Vladimir Sizikov
Assignee: Thomas E Enebo
{code}
require 'delegate'
class MyDelegator < Delegator
attr_reader :__getobj__
def __setobj__(o)
@__getobj__ = o
end
end
d = MyDelegator.new(10)
d.freeze ## fails HERE
{code}
An attempt to execute the example above leads to:
{noformat}
jruby --1.9 deleg.rb

This also causes LOTS of new rubyspec failures for Delegate library.
