That looks like a new property in Spring 3... we should add that option to
camel-jms but for now you should be able to make your own custom
JmsConfiguration class (extending the Camel JmsConfiguration one) and
override configureMessageListenerContainer to set up your idleConsumerLimit
value. You can use a custom JmsConfiguration like this:
<bean id="jmsConfig" class="com.foo.MyJmsConfiguration">
<property name="connectionFactory" ref="jmsConnectionFactory"/>
<property name="idleConsumerLimit" value="10"/>
<property name="concurrentConsumers" value="2"/>
<property name="maxConcurrentConsumers" value="20"/>
</bean>
<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig"/>
</bean>
