The JMS pool should offer a configuration option 'Connection Lifetime' that would limit the life time of a connection in the pool. Once the 'Connection Lifetime' limit has been reached the connection should be terminated regardless whether it is in use or idle. The count down on 'Connection Lifetime' should start from the moment the connection has been created. Please note that the 'Connection Lifetime' property should apply to individual connections and not to the whole pool.
The idea behind it this request is that it would force the client to reconnect to cluster hopefully rebalancing connections among brokers.
