I create a simple unit test to show my problem in VS2010 , coded in c#.
The idea of my test is as follow :
1. Send some message to the broker by web console.
2. Start a durable subscriber , and receive the test messages.Then call message.acknowledge() on the last message received.
3. Close the connection of the durable subscriber and start listening again.
the session is using individual ack mode. Since the individual ack mode acknowledges each message individually, I would expect that only the last message is acked , so after restart the subscriber, the test messages except the last one should be received again. However, the fact is every message is acked and
none test message is received the second time.
Generally speaking, My unit test compare the number of message received before ack the last message and after ack the last message. What I am expecting is the second time I will receive one less message but the fact is I receive 0 message.
