如何避免openssl上的jruby的错误文件描述符？

我在一个java swing应用程序中，它的WebService客户端在jruby中实现。用例是用户单击一个按钮，相应的控制器将打开一个新的线程，并且此线程从本地数据库获取一个列表，并且列表中的每个项目都会运行一个jruby脚本（通过ScriptingContainer）。如何避免openssl上的jruby的错误文件描述符？

总是第2级或3的呼叫JRuby是不成功的，但然后它抛出：

这里是一个迭代针对每个项目的代码：

public String createMsgAndSend(RouteInfo routeInfo) throws IOException { 
    ScriptingContainer container = new ScriptingContainer(LocalContextScope.CONCURRENT); 
    String code = null; 
    try { 
     container.put("info", new Info()); 
     container.put("route_info", routeInfo); 
     container.put("logger", LoggerFactory.getLogger("RubyClient")); 
     container.put("user", UserHolder.getCurrentUser() 
       .getUser()); 
     container.put("pwd", UserHolder.getCurrentUser().getPwd()); 
     RubyObject response = (RubyObject) container.runScriptlet(
       PathType.CLASSPATH, "send_request_for_app.rb"); 
     Ruby ruby = container.getRuntime(); 
     boolean success = response.callMethod("fetch", 
       RubySymbol.newSymbol(ruby, "success")).isTrue(); 
     LOGGER.info("Success?: " + success); 
     String error = (String) response.callMethod("fetch", 
       RubySymbol.newSymbol(ruby, "error")).asJavaString(); 
     if (success && error.isEmpty()) { 
      code = (String) response.callMethod("fetch", 
        RubySymbol.newSymbol(ruby, "code")).asJavaString(); 
      LOGGER.info("Response code: " + code); 
     } else { 
      throw new ServiceException(routeInfo, error); 
     } 
    } finally { 
     if (container != null) { 
      container.resetWriter(); 
      container.resetErrorWriter(); 
      container.clear(); 
      container.terminate(); 
     } 
    } 
    return code; 
}

JRuby的净/ http代码抛出异常：

 http= Net::HTTP.new(uri.host, uri.port) 
     http.use_ssl = true 
     http.ssl_version = 'SSLv3' 
     http.open_timeout= 5000 
     http.cert = OpenSSL::X509::Certificate.new(pem) 
     http.key = OpenSSL::PKey::RSA.new(pem, pem_key) 
     http.verify_mode = OpenSSL::SSL::VERIFY_PEER 
     request = Net::HTTP::Post.new(uri.request_uri) 
     http.finish if http.started?

我怀疑这可能与java线程有关，bu不知道问题出在哪里。我该如何避免这个坏文件描述符异常？

前段时间我和jruby有过这个非常相同的错误。我也得到了“坏文件描述符”异常。这是一个带有运行jruby脚本的线程的swing应用程序，我在调用jruby之后放置了一个睡眠以允许关闭脚本连接，但问题仍然存在。最后，我们在纯java中实现了所有的东西。祝你好运！ – Walt

试图添加2秒的睡眠。在container.terminate之后，但仍然发生错误。 – tramuntanal

也做了一个没有线程的测试类的调用，它重复了10次对容器的相同调用，并且它工作。 – tramuntanal

我回答我自己的问题：这是openssl库中的一个bug。在jruby邮件列表中提问，他们建议升级。升级到JRuby 1.7.5解决了问题！
