AspectJ EDT-Checker 代码问题

我目前正在使用 Alexander Potochkin 的 AspectJEDT 检查器代码 http://weblogs.java.net/blog/alexfromsun/archive/2006/02/debugging_swing.html（相关代码在帖子底部）。

这段代码（根据我对 AspectJ 的了解）抱怨任何未在 Swing EDT 中发生的 JComponent 方法调用或构造函数调用。

但是，以下仅抱怨 JList 构造函数，而不是 JFrame 构造函数。谁能告诉我为什么？谢谢！

package testEDT;

import javax.swing.DefaultListModel;
import javax.swing.JFrame;
import javax.swing.JList;

public class TestEDT{

    JList list;
    final JFrame frame;

    public TestEDT() {
        DefaultListModel dlm = new DefaultListModel();
        list = new JList(dlm);
        frame = new JFrame("TestEDT");
    }

    public static void main(String args[]) {
        TestEDT t = new TestEDT();
        t.frame.setVisible(true);
    }
}

Alexander Potochkin 的 AspectJ 代码：

package testEDT;

import javax.swing.*;

/**
 * AspectJ code that checks for Swing component methods being executed OUTSIDE the Event-Dispatch-Thread.
 * 
 * (For info on why this is bad, see: http://java.sun.com/products/jfc/tsc/articles/threads/threads1.html)

 */
aspect EdtRuleChecker{
    /** Flag for use */
    private boolean isStressChecking = true;

    /** defines any Swing method */
    public pointcut anySwingMethods(JComponent c):
         target(c) && call(* *(..));

    /** defines thread-safe methods */
    public pointcut threadSafeMethods():         
         call(* repaint(..)) || 
         call(* revalidate()) ||
         call(* invalidate()) ||
         call(* getListeners(..)) ||
         call(* add*Listener(..)) ||
         call(* remove*Listener(..));

    /** calls of any JComponent method, including subclasses */
    before(JComponent c): anySwingMethods(c) && 
                          !threadSafeMethods() &&
                          !within(EdtRuleChecker) {
        if ( !SwingUtilities.isEventDispatchThread() && (isStressChecking || c.isShowing())) {
            System.err.println(thisJoinPoint.getSourceLocation());
            System.err.println(thisJoinPoint.getSignature());
            System.err.println();
        }
    }

    /** calls of any JComponent constructor, including subclasses */
    before(): call(JComponent+.new(..)) {
        if (isStressChecking && !SwingUtilities.isEventDispatchThread()) {
            System.err.println(thisJoinPoint.getSourceLocation());
            System.err.println(thisJoinPoint.getSignature() + " *constructor*");
            System.err.println();
        }
    }
}

JFrame不是 的子类JComponent, but JList is.
