The reason for backing out EE 9 support is because there are too many issues with running it on various platforms, for example
    - it breaks the quickstarts
    - we cannot do releases until we have a working LRA implementation
    - the coordinator resource is used by various community users and we do not wish to break their applications without offering them an alternative
    - the coordinator-quarkus maven model does not work
    - the change severely restricts which JAX-RS servers are able to run the coordinator

    Until there is better support for Jakarta APIs on our target run-times we will choose byte code transformation - and the alternative of using a branch for EE 9 support is too much overhead.
