我在 Primavera P6 8.1 安装中遇到空指针异常。该异常仅发生在 Web 客户端的一个部分：应用程序设置。P6 Web 和 P6 API 部署在 Windows Server 2008 R2 安装上运行的同一 WebLogic (10.3.5) 节点上。我已经使用同一个软件堆栈完成了这个安装十几次，并且在任何其他安装中都没有这个问题。

下面的确切错误：

问题最终是安装在客户端机器上的 Java SE 客户端。高于 6_u32 的 Java 版本似乎不能很好地与 P6 8.1 配合使用。通过卸载 Java 客户端并访问 P6 Web，系统提示我安装 Java 的早期版本。

一旦安装了早期的 Java 版本，P6 web 的全部功能就可用。
