从浏览器(或从网络启动)运行JavaFX应用程序时，我遇到了一些奇怪的JSoup问题。
当我从IDE内部运行(Eclipse或Netbeans)或作为独立应用程序运行时，它可以正常运行。当我尝试以网络启动方式或从浏览器(Chrome)运行时，JSoup随机抛出“java.io.IOException:流已关闭”。
我要解析的站点是thepiratebay.sx。第一次运行应用程序(从浏览器)时，出现此错误。在应用程序运行的情况下，如果我尝试再次解析，那有时会奏效。
JSoup代码:
try {
//TODO: Change to HttpFetcher. This method is reporting "stream is closed" when running on browser
Connection con = Jsoup.connect(url)
.timeout(HTTP_TIMEOUT)
.userAgent(UserAgentGenerator.getUserAgent())
.followRedirects(false);
doc = con.get();
System.out.println("Fetching... " + url);
} catch (IOException e) {
e.printStackTrace();
System.out.println("Parser connect must have timed out, no results. " + url);
fetchFailed[i] = true;
continue;
}
finally {
i++;
if (CommonTFUtils.isAllTrue(fetchFailed)) {
throw new HttpException("Fetcher failed on every URL of " + response.getSite_name());
}
}
并抛出异常:

有谁知道这可能是什么原因？
提前致谢。
最佳答案
我想我找到了解决方案。在致电JSoup之前，请先放置此代码。显然，Applet和Web Start将此值设置为true。现在，我想知道为什么Sun强制您非静态地访问静态变量。
new URL("jar:file://dummy.jar!/").openConnection().setDefaultUseCaches(false);
缓存URL并将其视为异常时，JSoup不能很好地处理。
