The best way to monitor for connection exception is setting an exception listener, for example:

ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("jmsContextName");
        connection = connectionFactory.createConnection();
        connection.setExceptionListener(new ExceptionListener() {
            @Override
            public void onException(JMSException exception) {
                logger.error("ExceptionListener triggered: " + exception.getMessage(), exception);
                try {
                    Thread.sleep(5000); // Wait 5 seconds (JMS server restarted?)
                    restartJSMConnection();
                } catch (InterruptedException e) {
                    logger.error("Error pausing thread" + e.getMessage());
                }
            }
        });
        connection.start();
