【问题描述】：
不知何故，从今天开始，我的 Cucumber 代码出现以下错误 -
Selenium::WebDriver::Error::WebDriverError: 意外响应，code=502，content-type="text/html" 然后是页面的整个 HTML 文本。
这是完整的 IRB 控制台交互 -
C:\jruby-1.6.5\bin\jruby.exe --1.8 -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/jruby-1.6.5/bin/jirb - prompt simple

?> require "watir-webdriver"

?> @browser = Watir::Browser.new :ie

从今天早上开始突然发生这种情况，所以，我的问题是.. error code = 502 是什么意思？如果您查看此日志的顶部 - 它说
Selenium::WebDriver::Error::WebDriverError: unexpected response, code=502
那么，这是什么意思？哪里有问题？是代理问题还是别的什么？ 我尝试了不同的浏览器并遇到同样的问题？
更新 -
有趣的是 - 当我将我的 SDK 从 JRuby 1.5.6 更改为 Ruby 1.87 时，它运行良好...问题仅出在 JRuby 上...与 Ruby SDK 相同的事情运行良好...我试过了各种版本的 JRuby .. 像 1.6.5 和 1.6.7，它抛出了同样的错误，但是当我尝试 1.8.7 时它工作正常 - 它打开浏览器没有错误 -
这是 Ruby 1.8.7 的代码
C:\Ruby187\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/Ruby187/bin/irb --prompt simple
>> require "rubygems"
=> true
?> require "watir-webdriver"
=> true
?> @browser = Watir::Browser.new :ie
=> #<Watir::Browser:0x2e18b00 url="http://localhost:5555/" title="WebDriver">
?> @browser = Watir::Browser.new :ie
=> #<Watir::Browser:0x2ef07a0 url="http://localhost:5555/" title="WebDriver">

当我的环境设置了 http_proxy/https_proxy 的 FWIW 时，我得到了这个
