I did the following to make this issue gone. I am not quite certain that if 
every steps needed to be done or not.

1. I added a CountDownLatch in BlockingCommandBasedWSHumanTaskHandler and let 
my main thread to wait for it. In the GetCompletedTaskResponseHandler and 
GetResultContentResponseHandler handler I execute countDown based on the result 
to release the lock to ensure the response handler completed before I dispose 
the session in main thread.

2. I move the transaction scope to wrap my whole complete task logic.

3. I also find that it was triggering multiple callback to TaskCompletedHandler 
due to some reason. I partially fix that part.
