Possible memory leak in java.util.ConcurrentHashMap from org.apache.camel.impl.SharedPollingConsumerServicePool

I am using dynamic consumers like below:

                <simple>mqjmsComponent:queue:${header.queuename}?selector=orderId%3D'${in.header.orderId}'</simple>

I found the increasing memory usage of org.apache.camel.impl.SharedPollingConsumerServicePool.
this issue can be reproduced through the attached project.
