Description

While working on CAMEL-17945, I realized that the tests with the scope PER_CLASS leveraging the MockEndpoint to define their assertions can fail randomly because of a race condition issue. Indeed, with the current code, a message of a previous test method can potentially call the method countDown on the latch of the following test method causing unexpected behavior.
