Our JVx connection implementation for vert.x is up-to-date. It's now based on vert.x 3.0. We support http and socket connections - no API changes.
Updating to vert.x 3.0 from 2.2 was not funny because package structure was changed and some APIs as well. Whatever, it's working.
If you're interested in our vert.x implementation, check the github repository because we don't offer binaries.
