RabbitMQ - How i catch ForgivingExceptionHandler?

Question

I'm trying to catch/cover all unexpected error such as error connection in rabbitmq. i've tried all what i think is related Exception (Exception, IOException, SocketException) even the general exception itself (all of this is not catching the error) so i can prefer other flow, maybe as example: doing log submit using 3rd party system, or notify admin via email while maintain code to reconnect for 3 more times instead showing this error message and stopping all execution.

Here's the uncatched error message :

16:27:51.476 [AMQP Connection 192.168.7.167:5672] ERROR com.rabbitmq.client.impl.ForgivingExceptionHandler - An unexpected connection driver error occured

Here's my code :

    package TestPackage;

    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.ConnectionFactory;

    import java.io.FileInputStream;
    import java.io.IOException;
    import java.net.SocketException;
    import java.util.Properties;
    import java.util.concurrent.TimeoutException;

    public class TestQueueSend {
        static ConnectionFactory rbmqFactory;
        static Connection rbmqConn;
        static Channel rbmqChannel;

        public static void main(String[] args){
            Properties rabbitMQConf = new Properties();
            try {
                rabbitMQConf.load(new FileInputStream("./config/rabbitmqconf.properties"));
            } catch (IOException errorLoadRabbitMQConfig) {
                errorLoadRabbitMQConfig.getStackTrace();
            }

            rbmqFactory = new ConnectionFactory();
            rbmqFactory.setUsername(rabbitMQConf.getProperty("rabbit_mq_username"));
            rbmqFactory.setPassword(rabbitMQConf.getProperty("rabbit_mq_password"));
            rbmqFactory.setVirtualHost(rabbitMQConf.getProperty("rabbit_mq_virtualHost"));
            rbmqFactory.setHost(rabbitMQConf.getProperty("rabbit_mq_host"));
            rbmqFactory.setPort(Integer.parseInt(rabbitMQConf.getProperty("rabbit_mq_port")));

            System.out.println("Running RabbitMQConnection!");

            try {
                System.out.println("Connection START : " + rabbitMQConf.getProperty("rabbit_mq_host"));
                rbmqConn = rbmqFactory.newConnection();

                System.out.println("Create Channel");
                rbmqChannel = rbmqConn.createChannel();

                String queueName = "queueTest";
                String queueContent = "Kasur ini rusak";

                System.out.println("Queue Declare");
                rbmqChannel.queueDeclare(queueName,false,false,false,null);
                rbmqChannel.basicPublish("",queueName,null,queueContent.getBytes());

                System.out.println(" [x] Sent '" + queueContent + "'");

                rbmqChannel.close();
                rbmqConn.close();
            } catch(SocketException errorSocketCatch) {
                System.out.println("ERROR_SOCKET");
                System.out.println(errorSocketCatch.getMessage());
            } catch(IOException errorIOCatch) {
                System.out.println("ERROR_IO");
                System.out.println(errorIOCatch.getMessage());
            } catch (TimeoutException errorTimeoutCatch) {
                System.out.println("ERROR_TIMEOUT");
                System.out.println(errorTimeoutCatch.getMessage());
            } catch (Exception errorGeneric) {
                System.out.println("ERROR_GENERIC");
                System.out.println(errorGeneric.getMessage());
            }
        }
    }
