Description

In an attempt to ensure proper error handling once a Camel route would reach its configured Resilience4j Bulkhead limit, it was experienced that regardless of Bulkhead configuration, the limit was never upheld. Seemingly the Bulkhead has no effect within the circuit breaker.

The context in which the bug was experienced:
Spring Boot 2.4.2, Apache Camel 3.7.1 (reproducer tested using 3.7.2 as well).

A reproducer Maven project can be found here: sys-jdi/camel-bulkhead-test: Test of Resilience4J in Spring Boot application using Apache Camel.
