    Description

      A concurrent access exception occurs during our load tests while consuming messages from a rabbitmq queue.

      The call stack embedded below shows that the issue is related to an "optimization" which was introduced in https://issues.apache.org/jira/browse/CAMEL-11330 to replace a ConcurrentHashMap with a regular one from version 2.19.5 to 2.20.0 onward.

      The faulty code is still present in latest 2.22.0.
