Mysterious IllegalStateException - cannot find ref to ack
lolkat Mar 6, 2013 1:32 PMI am using hornetq version 2.2.14 embedded in our application using only the core API. I have a single consumer on a single queue, receiving messages from a producer on the same machine in another application.
Occasionally (seemingly at random) I am receiving this exception at the console. I am also seeing some issues where messages appear to not be delivered to my consumer, and due to the timing of this exception, I suspect the two may be related.
Any hints on what the issue might be or where to start debugging it?
