Description

Minimal demonstration code:

########
require 'webrick'

class BugDemonstrator < WEBrick::HTTPServlet::AbstractServlet
def do_GET(request, response)
response.body = ''
response.status = 204
response.content_length = 0
end
end

server = WEBrick::HTTPServer.new(:Port => 8080, :AccessLog => [])
server.mount "/", BugDemonstrator
trap("INT") do
server.shutdown
end
server.start
########

Output when run, connecting to localhost:8080 to issue an HTTP GET:

$ ruby webrickbug.rb

I'm doing literally what the warning message says to do -- i.e. setting the content-length of the response -- but I'm still getting the warning.
