Spring mvc Camel RouteBuilder rabbitMQ Connection reset exception - spring

Question

I have moved from spring 4.x to 5.2.0 and to camel 2.21.0,
during the patching process of the packages,
rabbitmq client began to throw the following exceptions:
com.rabbitmq.client.impl.ForgivingExceptionHandler
An unexpected connection driver error occurred (Exception message: Connection reset)
Connection failed, will retry in 5000ms

the RouteBuilder is like the following:
String conStr = "rabbitmq:sheker?hostname=%s"
+"&portNumber=%s"
+"&username=%s"
+"&password=%s"
+"&queue=%s"
+"&routingKey=%s"
+"&autoDelete=false"
+"&concurrentConsumers=%d";
from(String.format(conStr, hostname, port, username, password, queueName, queueName, queueConcurrentConsumers))
.throttle(throttleRequestCount)
.timePeriodMillis(throttleInterval)
.bean(Processor.PROCESSOR_BEAN_NAME);
the consumer is NOT created and messages are NOT coming through - and that IOException occurs - how can I fix that?
EDIT:
I think the issue is that my rabbit is working only over SSL connection,
so I tried the following:
<rabbit:connection-factory
id="defaultConnectionFactory"
channel-cache-size="5"
addresses="${addresses}"
password="${password}"
username="${username}"
connection-factory="sslConnectionFactory"/>
<bean id="sslConnectionFactory" class="com.sheker.MySSLConnectionFactory">
<constructor-arg>
<value>${useSsl}</value>
</constructor-arg>
<constructor-arg>
<value>${keystore}</value>
</constructor-arg>
<constructor-arg>
<value>${cert}</value>
</constructor-arg>
<beans:property name="requestedHeartbeat" value="60"/>
</bean>
import com.rabbitmq.client.ConnectionFactory;
public class MySSLConnectionFactory extends ConnectionFactory {
public SSLConnectionFactory(final boolean useSsl, final String keystore, final String cert) {
if (useSsl) {
useSslProtocol(new HttpUtil(keystore, cert).createSslContext());
}
}
}
String connectionStr = "rabbitmq:sheker?"
+"queue=%s"
+"&autoDelete=false"
+"&concurrentConsumers=%d"
+"&connectionFactory=#defaultConnectionFactory";
but I get even more exceptions:
