thread wait

Hi All,

I have a problem with suspending a thread.

As suspend() has deprecated I am trying to use the wait() - notify()
combination, but after the thread pauses it won't resume again.

Here is my code:

The two button listeners that should proceed the wait and notify
actions:

    /**
     * Start button listener
     */
    class startListener implements ActionListener {

        public void actionPerformed (ActionEvent e) {

            ta.append("DynamicPathGenerator> simulation started\n");
            threadsSuspended = false;

            if(!clock.isAlive()) {

                clock.start();

            }
            else {

                synchronized(this) {
                    notifyAll();

                }
            }

        } // method actionPerformed

    } // class startListener

    /**
     * Stop button listener
     */
    class stopListener implements ActionListener {

        public void actionPerformed (ActionEvent e) {

            ta.append("DynamicPathGenerator> simulation stopped\n");

            threadsSuspended = true;

        } // method actionPerformed

    } // class stopListener

The run method

    public void run()
    {
        try {

        while(true)
        {
            this.putText("F\n");

                this.counter++;
                this.putText(new Integer(counter).toString());
                Thread.sleep(clock_period);
                synchronized(this) {
                    while (threadsSuspended)
                        wait();
                }

        } // while

        } catch (InterruptedException e) {

        }

        return;

    } // method run

I have a boolean threadsSuspended = true;

variable at the initialization of the class.

The thread is initialized by:

Thread clock = new Thread(this);

Does anyone have a clue why the code is not working?

Thanks for your help!

Best,
