Notes on running the tests with Derby's Embedded Server

1) The default goal (torque-test:run) will fail with the embedded driver because
     it is hard to shutdown the embedded server between operations.
     
     In order to test the embedded driver, the four sub-goals need to be run
     separately.  E.g:
     
     maven -Dtorque.test.profile=derby torque-test:pre-test
     maven -Dtorque.test.profile=derby torque-test:test
     maven -Dtorque.test.profile=derby torque-test:post-test1
     maven -Dtorque.test.profile=derby torque-test:post-test2

 2) The Bookstore database directory should be manually deleted between
     test case runs because some tables can not be dropped.
