访问限制：类型“应用程序”不是 API（对所需库 rt.jar 的限制）背景：日食访问限制 问题溶液
代码如下：
package mscontroller;
import javax.swing.*;
import com.apple.eawt.Application;
public class Main {
public static void main(String[] args)
{
Application app = new Application();
app.setEnabledAboutMenu(true);
AMEListener listener = new AMEListener();
app.addApplicationListener(listener);
JFrame mainFrame = new JFrame("Application Menu Example");
mainFrame.setSize(500, 500);
mainFrame.setVisible(true);
}
}
这是错误：
Exception in thread "main" java.lang.Error: Unresolved compilation

日食是这样说的：
访问限制：类型'Application'不是API（对所需库'/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/rt.jar'的限制）
