使用 URLConnection 时出现 java.lang.NegativeArraySizeException

Question

我正在尝试创建一个 Telegram 机器人并且我的代码已经可以运行，但突然我无法启动我的程序，因为它因以下错误而崩溃。我没有更改任何代码或做任何事情。

也许这是操作系统的错误？

有时代码会导致段错误:

重现错误的最少代码:

import java.net.URL;
import java.net.URLConnection;
import java.io.IOException;
import java.net.MalformedURLException;

class test {
    public static void main(String[] args) throws IOException, MalformedURLException {
        URL url = new URL("https://api.telegram.org/bot<ID>/getUpdates?offset=0");
        URLConnection c = url.openConnection();
        c.connect();
    }
}

我在 Fedora 25 和 OpenJDK 上运行代码。

检查您的 NSS 库版本，nss 3.28 似乎破坏了 java 的内容。它也发生在 gentoo 上:https://bugs.gentoo.org/show_bug.cgi?id=605430

降级到 nss 3.27.x 也为我和其他人修复了它。
