FULL PRODUCT VERSION :
This issue is there starting from JDK 1.7

A DESCRIPTION OF THE PROBLEM :
EventQueue.pop() does not stop dispatch thread as specified in the API documentation. I have checked in the source code, and observed that below line of code is missing from JDK 1.7.

dispatchThread.stopDispatching();

the above line of code is present in JDK 1.6 and earlier versions.

REGRESSION. Last worked in version 6u45

ADDITIONAL REGRESSION INFORMATION:
JDK 6 and earlier versions

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run below code in JDK 7 and later versions
Run below code in JDK 6 and prior versions

SwingUtilities.isEventDispatchThread() - returns different values after push/pop

package com.dev.test;

import java.awt.AWTEvent;
import java.awt.EventQueue;
import java.awt.Toolkit;
import java.lang.reflect.InvocationTargetException;

import javax.swing.SwingUtilities;

public class EventQueueTest {
    public static void main(String[] args) throws InterruptedException, InvocationTargetException {
     setQueue();
     System.out.println(Thread.currentThread());
    
     System.out.println("aa"+SwingUtilities.isEventDispatchThread());
    
    
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                 System.out.println("aa11"+SwingUtilities.isEventDispatchThread());
                 setQueue();
                 MyEventQueue eventQueue = (MyEventQueue)Toolkit.getDefaultToolkit().getSystemEventQueue();
                
System.out.println("Run");
System.out.println(Thread.currentThread());
System.out.println("aa1"+SwingUtilities.isEventDispatchThread());
eventQueue.pop();
System.out.println(Thread.currentThread());
System.out.println("aa3"+SwingUtilities.isEventDispatchThread());
                }
            
        });
        
        System.out.println(Thread.currentThread());
        System.out.println("aa2"+SwingUtilities.isEventDispatchThread());
    }

    private static EventQueue setQueue() {
        EventQueue eventQueue = Toolkit.getDefaultToolkit().getSystemEventQueue();
        eventQueue.push(new MyEventQueue());
        return eventQueue;
    }

    private static class MyEventQueue extends EventQueue {
        public void postEvent(AWTEvent theEvent) {
            System.out.println("Event Posted");
            super.postEvent(theEvent);
        }
        
        public void pop() {
            super.pop();
        }
    }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
SwingUtilities.isEventDispatchThread() - should return false after push/pop
ACTUAL -
SwingUtilities.isEventDispatchThread() - return true after push/pop

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No errors

REPRODUCIBILITY :
This bug can be reproduced always.
