JAVA + jsoup + httpUnit 爬虫报错

Question

String sinaLoginUrl="http://apps.evozi.com/apk-downloader";
WebClient client=new WebClient();
client.getOptions().setCssEnabled(false);
client.getOptions().setJavaScriptEnabled(true);//设置成true就报错
HtmlPage loginPage = client.getPage(sinaLoginUrl);
HtmlButton loginButton= (HtmlButton) loginPage.getElementById("download_apk");
HtmlPage result = loginButton.click();
System.out.println(result.getUrl().toString());

错误信息：
com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot find function addEventListener in object [object HTMLDocument]. (http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js#2)

是否不认识jquery的标签导致的呢，请教各位
