Figure 9-13.
The database contents prior to, and after, running our test
Figure 9-14 shows a sample run of the test harness. As expected, one of the clients (client
2 in this particular run) missed out on their first attempt to rent the movie, and a different
client (client 3) missed out on their second attempt to rent the movie.

Caution
Although we have made a reasonable attempt to make a multithreaded networked test harness
that will produce repeatable results, you should be aware that the JVM thread scheduler and network
latency may result in slightly different results.
