Ran into the following problem with net http in Ruby 187 pl248

require net/http.rb
n = Net::HTTP.new('server-that-is-not-listening-on-port-eighty')
n.request_head('/')

Prior to this change:
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=25851 the
above code results in an:

Errno::ECONNREFUSED: Connection refused - connect(2)


After the change I receive:

NoMethodError: undefined method `closed?' for nil:NilClass


From line 1060 of net/http.rb. It looks like the code was intended to close
sockets in the event of an error, but it assumes the socket actually exists

Yes, I can reproduce.

Indeed, this looks like unintentional change to me and somewhat
unintuitive. I think, you should file a report on Redmine for this or
raise it on ruby-core mailing list.

Thanks for taking the time to respond Hemant.

I've added a redmine ticket for it here
