> When more than 75 percent prefetch messages are delivered,the standard ack occurs.
> If consumer/recipient fails after that, the rest messages will be one part of the whole.
> New coming up consumer will discard the rest messages because it's expected to read sequential messages from seq 0.
> From the view of the end user, the data transfered by JMS Stream is incomplete 
> and data is lost in this case.
