> ConsumeJMS processor uses auto-acknowledge mode. Unlike the deprecated GetJMSQueue processor it does not provide a way to specify a different ACK mode (i.e. client-acknowledge.) Using auto-acknowledge, acknowledges message receipt from JMS *before* the messages are actually added to the flow. This leads to data-loss on NiFi stop (or crash.)
> I believe the fix for this is to allow the user to specify the ACK mode in the processor configuration like is allowed by the GetJMSQueue processor.
