WSO2 ESB EntitlementMediator評估策略時發生錯誤

我跟着this guide將ESB與Identity Server集成在一起。WSO2 ESB EntitlementMediator評估策略時發生錯誤

我試圖wso2esb-4.6.0和wso2is-4.1.0

以下是我的步驟：

配置WSO2身份Server作爲XACML引擎和啓動標識服務器。
配置WSO2 ESB中的授權調解器並啓動ESB。
在IDE中運行客戶端代碼。

但ESB EntitlementMediator發生錯誤。

在ESB命令窗口，以下錯誤發生：

在IS命令窗口中，發生如下錯誤：

在客戶端IDE，發生在控制檯以下消息：

這似乎是在下一個ESB版本（4.7.0）中修復的錯誤。它將在不久的將來發布。見[1]。

謝謝你的建議。但是我怎樣才能獲得ESB版本（4.7.0）來嘗試呢？ – iceguo
