JRuby:Watir在启动浏览器时挂起

Question

我有Windows 7企业版,我正在尝试运行JRuby.我为Ruby(1.9.3),Java(jdk - 1.6.7)和JRuby(1.7preview)设置了我的环境变量.我有一个网络驱动器,但我创建了一个HOME系统变量似乎正在工作,因为我可以成功下载Ruby和JRuby的宝石,并将它们保存到我的本地驱动器.

当我尝试启动浏览器(即firefox,chrome)时,似乎挂起了JRuby,但不是Ruby.以下是JRuby尝试执行10分钟后的跟踪:

irb(main):003:0> require 'rubygems'
=> false
irb(main):004:0> require 'watir-webdriver'
=> true
irb(main):005:0> b = Watir::Browser.new :ie
IRB::Abort: abort then interrupt! *<--Note I killed the process after 10 minutes*

JRuby似乎挂了,因为它正在寻找一个开放的端口.我们必须为我们的网络使用HTTP代理,我也为此设置了一个系统变量.我真的不知道为什么Watir会为Ruby而不是JRuby工作.

我有类似的问题 - selenium-webdriver在使用JRuby和Java 6时没有打开浏览器,但是它与Java 7一起工作.

我发现Java 6似乎有一些IPv6问题,并且在IPv6接口上找不到自由端口.

解决办法是添加-Djava.net.preferIPv4Stack=true到JAVA_OPTS告诉Java的喜欢IPv6上的IPv4可能的情况下.
