Android - Nougat 上的 IllegalAccessError

Question

我的应用程序在 5+ 和 6+ 上完美运行，但在 7 上却不行。当应用程序尝试登录服务器时抛出此异常:

我已经在我的模拟器上试过了，总是在 Nougat 上崩溃，但在任何以前版本的 Android 上都没有崩溃。

他们是否在分子水平上改变了什么？

这是抛出异常的类:

public class Connection extends Thread {

public static Document connectToAPIURL(String url, Context context) {
    try {
        Log.i("URLApi", url);
        if (checkInternetConnection(context)) {
            return new SAXBuilder().build(HTTPS.getInstance().connection(url));
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    return null;
}

public static boolean checkInternetConnection(Context context) {
    ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = conMgr.getActiveNetworkInfo();
    if (activeNetwork != null && activeNetwork.isConnected()) {
        return true;
    }
    return false;
}

你能帮我解决这个问题吗？

谢谢!

我遇到了同样的问题。升级到 JDOM 2.0.6 即可解决问题。

来自 JDOM 发行说明:“修复问题 129 - Java 8 在 List 接口(interface)上引入了公共(public)排序方法。这与 ContentList 上的 protected 排序冲突”
