      Springboot reproducer attached. To test, run mvn clean test. With version.activemq set to 5.11.0.redhat-630396 in the parent pom, no duplicate suppression warnings / poison acks are observed. With 5.11.0.redhat-630416, we see duplicate suppression warnings in the debug logging.

      To rerun the test, delete all sub-directories under the jar module, update the version.activemq property and re-run mvn clean test.

      When testing scenarios with redelivery and with prefetch enabled (even with prefetch=1), duplicate suppression / poison acks are observed with versions 5.11.0.redhat-630396-02 and 5.11.0.redhat-630416. These are not observed in the unpatched 5.11.0.redhat-630396 version.
