 * is running, simply press <return> or any other key to end the application. To fully experience the
 * benefits of this solution, try halting/exiting the program in the middle of running it, comment out the
 * call to place new orders (the order() function call) and watch that the processing still continues
 * where it left off when you halted it. This is because the messages are persisted in the ActiveMQ queues.
