Javascript HtmlUnit大型异常日志试图获取加载了脚本的某些字段的网页的html

我正在尝试阅读网页的html。我认为有些字段是由脚本填充的，因为我可以在浏览器中清楚地看到它们，但在浏览网页时，它们的内容是空的。 当我尝试在下一个代码中使用HtmlUnit时，我在日志中遇到了一个很大的异常，我不知道如何修复它

这是我的密码：

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.DomNode;
import com.gargoylesoftware.htmlunit.html.DomNodeList;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class HtmlUnitTest {

    public static void main(String[] args) {

         /* turn off annoying htmlunit warnings */
        java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF);

        String searchQuery = "William Hill" ;

        WebClient client = new WebClient(BrowserVersion.CHROME);  
        client.getOptions().setCssEnabled(false);  
        client.getOptions().setJavaScriptEnabled(true);  
        try {  
          String searchUrl = "http://sports.williamhill.es/bet_esp/es/betting/t/338/LaLiga.html" + URLEncoder.encode(searchQuery, "UTF-8");

          HtmlPage page = client.getPage(searchUrl);
          client.waitForBackgroundJavaScriptStartingBefore(10000);

          final DomNodeList<DomNode> divs = page.querySelectorAll("tr.rowOdd");

          for (DomNode div : divs) {
                System.out.println(div.asXml());
            }


        }catch(Exception e){
          e.printStackTrace();
        }
        }


}

导入com.gargoylesoftware.htmlunit.BrowserVersion；
导入com.gargoylesoftware.htmlunit.WebClient；
导入com.gargoylesoftware.htmlunit.html.DomNode；
导入com.gargoylesoftware.htmlunit.html.DomNodeList；
导入com.gargoylesoftware.htmlunit.html.HtmlPage；
公共类HtmlUnitTest{
公共静态void main（字符串[]args）{
/*关闭恼人的htmlunit警告*/
getLogger（“com.gargoylesoftware”）.setLevel（java.util.logging.Level.OFF）；
字符串searchQuery=“William Hill”；
WebClient客户端=新的WebClient（BrowserVersion.CHROME）；
client.getOptions（）.setCssEnabled（false）；
client.getOptions（）.setJavaScriptEnabled（true）；
试试{
字符串搜索URL=”http://sports.williamhill.es/bet_esp/es/betting/t/338/LaLiga.html“+URLEncoder.encode（搜索查询，“UTF-8”）；
HtmlPage=client.getPage（searchUrl）；
client.waitForBackgroundJavaScriptStartingBefore（10000）；
final DomNodeList divs=page.queryselectoral（“tr.rowOdd”）；
for（DomNode div:divs）{
System.out.println（div.asXml（））；
}
}捕获（例外e）{
e、 printStackTrace（）；
}
}
}

以下是我得到的一个例外：
