Yes this was by design.   We added a new testsuite module for embedded tests, integration-tests-embedded, which tests Vertx, Undertow, Netty and Sun.  We needed to standardize the interface and functions to support that.

I guess this used to be done automatically in the past. Was this change in behaviour intentional?
