如何避免openssl上的jruby的錯誤文件描述符？

我在一個java swing應用程序中，它的WebService客戶端在jruby中實現。用例是用戶單擊一個按鈕，相應的控制器將打開一個新的線程，並且此線程從本地數據庫獲取一個列表，並且列表中的每個項目都會運行一個jruby腳本（通過ScriptingContainer）。如何避免openssl上的jruby的錯誤文件描述符？

總是第2級或3的呼叫JRuby是不成功的，但然後它拋出：

這裏是一個迭代針對每個項目的代碼：

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的淨/ http代碼拋出異常：

 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?

我懷疑這可能與java線程有關，bu不知道問題出在哪裏。我該如何避免這個壞文件描述符異常？

前段時間我和jruby有過這個非常相同的錯誤。我也得到了「壞文件描述符」異常。這是一個帶有運行jruby腳本的線程的swing應用程序，我在調用jruby之後放置了一個睡眠以允許關閉腳本連接，但問題仍然存在。最後，我們在純java中實現了所有的東西。祝你好運！ – Walt

試圖添加2秒的睡眠。在container.terminate之後，但仍然發生錯誤。 – tramuntanal

也做了一個沒有線程的測試類的調用，它重複了10次對容器的相同調用，並且它工作。 – tramuntanal

我回答我自己的問題：這是openssl庫中的一個bug。在jruby郵件列表中提問，他們建議升級。升級到JRuby 1.7.5解決了問題！
