Chris FWIW, the Get/PutJMS* are effectively deprecated processors since they only support one JMS provider (ActiiveMQ) and should not be used. Instead we recommend Publish/ConsumeJMS pair.
As to your question, which specific ACK mode you are inquiring about? As the doc currently states, the auto-ACK may loose messages. Is that what you are using?

Acknowledgement Mode Client Acknowledge • Client Acknowledge • Auto Acknowledge The JMS Acknowledgement Mode. Using Auto Acknowledge can cause messages to be lost on restart of NiFi but may provide better performance than Client Acknowledge. Can someone speak to how Acknowledgement Mode is handled by the ConsumeJMS processor? The reason I ask is that I seem to be losing messages on NiFi restart.
