release (see the "spring-integration-samples" JAR and source JAR). This sample is inspired by one of the samples

To run this demo, go to the "samples" directory within the root of the Spring Integration distribution. On
Unix/Mac you can run 'cafeDemo.sh', and on Windows you can run 'cafeDemo.bat'. Each of these will by default
create a Spring <interfacename>ApplicationContext</interfacename> from the 'cafeDemo.xml' file that is
in the "spring-integration-samples" JAR and hence on the classpath (it is the same as the XML above). However, a
copy of that file is also available within the "samples" directory, so that you can provide the file name as a
command line argument to either 'cafeDemo.sh' or 'cafeDemo.bat'. This will allow you to experiment with the
configuration and immediately run the demo with your changes. It is probably a good idea to first copy the
original file so that you can make as many changes as you want and still refer back to the original to compare.

When you run cafeDemo, you will see that all 100 cold drinks are prepared in roughly the same amount of time as
only 70 of the hot drinks. This is to be expected based on their respective delays of 700 and 1000 milliseconds.
However, by configuring the endpoint concurrency, you can dramatically change the results. For example, on my
machine, the following single modification causes all 100 hot drinks to be prepared before the 4th cold drink is
