Without JMX enabled on the broker; when the DB is shutdown and subsequently restarted the JDBCIOExceptionHandler does a shutdown and restart on the transport connector as expected.

However when JMX is enabled on the broker the transport connector fails to restart throwing the following exception and subsequently shutting down the broker
