Tracking a Route - Problem with losing messages

Steps to Reproduce

1. run as Local Camel Context some project (e.g. camel-spring)
2. open JMX Navigator View
3. navigate to Local Processes --> Local Camel Context --> Camel --> camel-1
4. invoke the context menu and select "Start Tracking"
5. navigate to endpoint src/data?noop=true only via clicking on '+'
6. send some messages to the endpoint note that expanded tree in JMX Navigator remains expanded
7. check Message View contains appropriate number of records
8. select the endpoint src/data?noop=true in JMX Navigator
9. send another message to the endpoint note that JMX Navigator is refreshed, items are collapsed) annoying
10. check Message View contains only last message. IMHO it is a bug. It should contain all messages not only the last one
