After testing the scenario below with version 5.10.0, I've found that the allowLinkStealing="true" appears to work properly only for the *first* reconnect; if the same MQTT client reconnects a second time (using the same client-id) the previous connection is not closed and I get the following error:
WARN | Failed to register MBean org.apache.activemq:type=Broker,brokerName=broker1,connector=clientConnectors,connectorName=mqtt,connectionViewType=clientId,connectionName=test1 Mark -- Are you seeing this in your environment? Does anyone know of a way to prevent or work around this? Thanks!
