Redelivery delay settings doesn't work on ActiveMQXAConnectionFactory - apache-camel

Question

I've been trying to configure a jms endpoint (activemq 5.7) in my camel context (camel 2.8) so it should use redelivery of messages on rollback. Unfortunately, it doesn't work as I've expected: it returns back a message to a queue, but a consumer takes the message in despite of specified delay parameters immediately after that.
My configuration is the following:
...
<bean id="jmstx" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsTxConfig" />
</bean>
<bean id="jmsTxConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsXaPoolConnectionFactory"/>
<property name="transactionManager" ref="osgiPlatformTransactionManager"/>
<property name="transacted" value="false"/>
<property name="cacheLevelName" value="CACHE_NONE"/>
<property name="concurrentConsumers" value="${jms.concurrentConsumers}" />
</bean>
<bean id="jmsXaPoolConnectionFactory" class="org.apache.activemq.pool.XaPooledConnectionFactory">
<property name="maxConnections" value="${jms.maxConnections}" />
<property name="connectionFactory" ref="jmsXaConnectionFactory" />
<property name="transactionManager" ref="osgiJtaTransactionManager" />
</bean>
<bean id="jmsXaConnectionFactory" class="org.apache.activemq.ActiveMQXAConnectionFactory">
<property name="brokerURL" value="${jms.broker.url}"/>
<property name="redeliveryPolicy">
<bean class="org.apache.activemq.RedeliveryPolicy">
<property name="maximumRedeliveries" value="-1"/>
<property name="initialRedeliveryDelay" value="2000" />
<property name="redeliveryDelay" value="5000" />
</bean>
</property>
</bean>
A small sample that demonstrates how I'm using the endpoint:
<route id="main-route">
<from uri="jmstx:queue:my-queue" />
<to uri="direct:subroute" />
...
<!-- some logic -->
</route>
<route id="subroute">
<from uri="direct:subroute" />
<transacted ref="PROPAGATION_MANDATORY"/>
...
<!-- Rollback on some condition -->
<rollback/>
...
</route>
Does anyone knows why it happens?
Thank you.

Yes, I encountered same problem.
After hacking the ActiveMQ source code, and adding some logging information, I found some evidences and googled the solution.
Just like the answer said:
https://developer.jboss.org/thread/266172
After setting cacheLevel to CACHE_CONSUMER on the activemq component, solved the problem.
ex:
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsPooledConnectionFactory" />
<property name="concurrentConsumers" value="1"/>
<property name="transacted" value="true"/>
<property name="cacheLevelName" value="CACHE_CONSUMER"/>
<property name="acknowledgementModeName" value="SESSION_TRANSACTED"/>
</bean>
