ConcurrentModificationException during route listing
Hi,
I am using camel version 2.15.1. Sometimes I see ConcurrentModificationException in logs with following trace. With test case of adding and listing routes concurrently I could not regenerate exception. Any idea about reason ?
Trace :

Re: ConcurrentModificationException during route listing
Posted by onders <on...@gmail.com>.
ConcurrentModificationException happens to be due the fact that you are
trying to modify the collection whereas you are traversing it.
It's hard to help you unless we know some details of design of your route.
If you can provide details, we can give it a shot..
