/**
 * Part of migration EJB testsuite (JBAS-7922) to AS7 [JIRA JBQA-5483]. This test covers jira AS7-687 which aims to migrate this
 * test to new testsuite.
 * Testing undeploying an app in middle of MDB onMessage function and checking whether all messages will processed correctly.
 *
 * Code sequence is:
 * 1. deploy the application
 * 2. send 1 "await" message
 *    => test waits to MDB would start with receiving the message
 * 3. undeploy the app (undeploy waits until onMessage finishes work)
 * 4. MDB transaction is timeouted which means that is marked as rollback only (no exception thrown)
 *    transaction timeout influences only incoming message (is putting back to queue) 
 *    the outgoing message is not "send" by XA aware connection factory
 *    when TM runs on JTS then sleep is interrupted with interrupted exception
 * 5. meanwhile sending 50 "50loop" messages
 * 6. MDB onMessage finishes ist work ("await" message is delivered to out-queue)
 *    and the undeployment of app could finish its work
 * 7. ensure that the undeployment is completed
 * 8. redeploy the application
 * 9. send 10 "10loop" messages
 * 10. check the test receives 62 messages:
 *    * 1 await
 *    * 50 do not lose
 *    * 10 some more
 *    * 1 await (redelivered message)
