Camel ActiveMQ connection creates lots of null transaction commits

Issue

• We have noticed in our environment that we get a lot of DEBUG level messages like.

2014-06-20 16:57:03,820 | DEBUG | Camel (Process) thread #205 - JmsConsumer[QUEUE.TestQueue] | ActiveMQSession      | 176 - org.apache.activemq.activemq-core - 5.7.0.fuse-71-047 | ID:3216-1403297317359-39:1:6 Transaction Commit :null

• While everything is working correctly, we believe we might be using transactions with Spring and ActiveMQ in camel incorrectly causing null transactions to created and committed continually.

• Below is our spring for creating the activemq bean for camel. Is this correct/best?

<bean class="org.apache.activemq.pool.PooledConnectionFactory" id="jmsConnectionFactory">
        <property name="connectionFactory">
          <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL">
              <value>${activeMQServer}</value>

            <property name="userName">
              <value>${activeMQServerUserName}</value>
            </property>
            <property name="password">
              <value>${activeMQServerPassword}</value>
            </property>
          </bean>
        </property>
