Which version of Camel are you using ? I just assume you are using Camel 2.3.0, as Claus did lots of work on Camel trunk, the stack trace can't match with current trunk code.
If I remember right , there is a timer thread to keep try redelivering the exchange, maybe that cause the ConcurrentModificationException. Can try to run your application with Camel 2.4-SNAPSHOT ? If the error still there, you can fill a JIRA and submit a small test case, so we can keep on digging it.
