the groovy test had a conditional to use 500 for testLatestDeps and 405 otherwise. I see you implemented that in the Jetty test, but that was not needed here as well? I assume not since the tests are all passing

It is not needed because of using a lambda in

    serverFactory.setProvider(
        (ExceptionMapper<Exception>)
            exception ->
                Response.status(500)
                    .type(MediaType.TEXT_PLAIN_TYPE)
                    .entity(exception.getMessage())
                    .build());

When choosing an exception mapper cxf inspects the exception mapper classes and ends up choosing between a built in mapper and our mapper. When using regular class it picks the built in one and when using lambda our one for the non standard http method test.

thank you for the explanation
