I've tried using the following simple ruby code on jruby-9.2.0.0 to authenticate with salesforce via Restforce(3.0.1) gem then try to subscribe to a push topic and it doesn't work and I get an error. See the steps to reproduce below with my expected behavior and actual behavior.

Note if needed I can add steps for the "Streaming API Developer Guide" part. Or maybe change to use another streaming api like twitter to make the repo more easier.

Steps to reproduce:

1. Use jruby-9.2.0.0
2. Install Restforce(3.0.1), faye (1.2.4), & pry (0.11.3 java)
3. Follow Streaming API Developer Guide - Quick Start Using Workbench
4. Use the follow ruby code in pry

require 'faye'
require 'eventmachine'
require 'restforce'

url = "https://na31.salesforce.com/cometd/36.0"

restforce = Restforce.new(
                  api_version: '36.0',
                  username: 'username,
                  password: 'password',
                  client_id: 'clientid',
                  client_secret: 'clientsecret')

authorization_hash = restforce.authenticate!

client = Faye::Client.new(url)
client.set_header('Authorization', "OAuth #{authorization_hash.access_token}")

EM.run {
	client.subscribe('/topic/AllAccounts') do |message|
		puts message
	end
}

5. Trigger an action to trigger the push notification

Expected:
{"event"=>{"createdDate"=>"2018-08-16T20:27:28.818Z", "replayId"=>41, "type"=>"created"}, "sobject"=>{"Id"=>"0013700000ZQWB9AAP", "Name"=>"asdf"}}

Actual:
ArgumentError: Invalid header value type
from org/ruby_http_parser/RubyHttpParser.java:478:in `header_value_type='

Notes:
If I repeat the steps above but use ruby 2.5.1 and it works fine. Would be happy to debug this but I'm still a novice for ruby. Also not sure if this is the proper place to put this bug. I'm also a novice to github.
