我正在尝试使用 HTMLUnit 获取此页面，但似乎 HTMLUnit 进入无限循环并崩溃。
我一直试图找到原因，但我放弃了。我试过了：
- 从 SVN HTMLUnit 获取最新代码
- 使用不同的浏览器
- 尝试调试，但我找不到原因。
如果我使用 webClient.setJavaScriptEnabled(false);
我可以获取该站点，但未执行重要的脚本。所以，问题在于 JavaScript。
这是一个运行到循环的示例代码：
String url = "http://www.tjpe.jus.br/processos/consulta1grau/oleConsultaProcesso.asp?
nume=00123335620128170990&modalidade=6";
final List collectedAlerts = new ArrayList();
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);
webClient.setThrowExceptionOnScriptError(false);
webClient.setAlertHandler(new CollectingAlertHandler(collectedAlerts));
webClient.waitForBackgroundJavaScript(10000);
webClient.waitForBackgroundJavaScriptStartingBefore(10000);
try {
final HtmlPage page1 = webClient
.getPage(url);
page1.asXml();
} catch (FailingHttpStatusCodeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
这是错误：
