Spring jms. How to not cache connection. Failover test

Question

I need to do some failover test in my app that uses spring JMS. I want to simulate broken TCP connection. Spring framework has two implementations of ConnectionFactory interface (SingleConnectionFactory and CachingConnectionFactory) and both of them cache connection. According to documentation they "... ignore calls to close()". So that I cannot debug and close that connection. I also don't have access to tools like wireshark and have no access to physical machine to unplug cable. Is there any way that I can simulate "interrupted connection"?

Call resetConnection().

/**
 * Reset the underlying shared Connection, to be reinitialized on next access.
 */
public void resetConnection() {
    synchronized (this.connectionMonitor) {
        if (this.target != null) {
            closeConnection(this.target);
        }
        this.target = null;
        this.connection = null;
    }
}
