Same issue here. Just created simple Verticle:

public class DatabaseVerticle extends AbstractVerticle {
    private SQLClient mySQLClient;

    @Override
    public void start(Future<Void> startFuture) throws Exception {

        JsonObject mySQLClientConfig = new JsonObject()
                .put("host", config().getString("mysql.host", "localhost"))
                .put("port", config().getInteger("mysql.port", 3306))
                .put("maxPoolSize", config().getInteger("mysql.maxPoolSize", 100))
                .put("username", config().getString("mysql.username", "user"))
                .put("password", config().getString("mysql.password", "password"))
                .put("database", config().getString("mysql.database", "dbName"))
                .put("charset", config().getString("mysql.charset", StandardCharsets.UTF_8.name()));

        mySQLClient = MySQLClient.createNonShared(vertx, mySQLClientConfig);

                Future<SQLConnection> future = Future.future();
        mySQLClient.getConnection(future.completer());
                future.compose(conn -> {
                        Future<Void> f = Future.future();
                         //Create some table
                        return f;
                }).setHandler(ar ->{
                        if(ar.failed()){
                               startFuture.fail(ar.cause());
                        }else{
                               startFuture.complete();
                        }
                });

Deployed verticle like this vertx.deployVerticle(new DatabaseVerticle(), new DeploymentOptions().setConfig(config())); and than exception was thrown.

Is there any fork that supports this?
