java无法初始化jNativeHook 2.0

Question

我正在尝试使用库JNativeHook 2.0拦截键盘事件，请参阅：

import org.jnativehook.GlobalScreen;
import org.jnativehook.NativeHookException;

public class MainApp {

    public static void main(String[] args) {
        try {
            GlobalScreen.registerNativeHook();
        }
        catch (NativeHookException ex) {
            System.err.println("There was a problem registering the native hook.");
            System.err.println(ex.getMessage());

            System.exit(1);
        }

        GlobalScreen.addNativeKeyListener(new Intercept());
    }

}

但当我尝试启动MainApp时，我发现了一个错误：

Informações: Library extracted successfully: /tmp/libJNativeHook-2.0.0.so (0xE9C5AD25418C597994B824E5A9D62858192227D).

挂钩设置记录器程序应由libuiohook在链接时定义。这可能与Issue #43有关
