试图在HTMLUnit中使用getPage时出现java ClassCastException

2 周，1 日 Questions & Answers 184

下面是我正在使用的简单代码片段：

final WebClient client = new WebClient();
final HtmlPage page = client.getPage("http://www.muthead.com/packs/simulator/12-tokearmy-pack");

这给了我以下信息：

奇怪的是，如果我关闭了http://google.com的链接，一切都正常。这是否意味着我试图链接的网页有问题？（即使是有效链接）

Python中文网

有 Java 编程相关的问题?
