Solace JMS issue

Hi @Havgi,
I tested this out locally and was not able to reproduce the error. Are you setting the Reconnect Retry Attempts + Wait time on the Connection factory or handling the reconnecting manually?

Also can you elaborate on what message id you're checking?

If it helps this is the code I used locally that properly reconnected:
