IncompatibleClassChangeError

Hi
Earlier we were using CamelSpringTestSupport based Junit test cases to test
the Camel route based on Camel 2.11 and everything worked fine. Recently we
upgraded Camel to 2.13 and we started getting the below error. Could you
please advice?

coded...from the header

ascending since it compares who is bigger not older
mock.expectsAscending(header("CamelFileLastModified"));

//Let's give it a couple of seconds
Thread.sleep(2000);
//Check all the conditions for me please ma'am

The error happens in the tearDown's super.tearDown() call.
