Are you really still using Vert.x 2 ?

Vert.x 3 issues and code would be here: https://github.com/vert-x3/vertx-mysql-postgresql-client/

I use vertx3.X. I copy it to new project.
<dependency> <groupId>io.vertx</groupId> <artifactId>vertx-mysql-postgresql-client</artifactId> <version>3.4.1</version> </dependency>
