Hi.

It's somewhat acceptable. If you close the connection explicitly then 
you know that every message you have published / every ack you have sent 
will have been received by the server by the time the close method returns.

If you just kill the program then that won't be true - in-flight 
publishes may be lost (obviously any that have been confirmed won't be). 
In-flight acks may also be lost (and hence the messages they are 
acknowledging will be redelivered). The server will log a warning. But 
that's all.

Cheers, Simon
