Object oriented boggle game with HTTP interface

A reactive object oriented implementation of the Boggle game with a HTTP interface. The latter is implemented with Vert.x.

It's written with minimalism, flexibility and object thinking in mind. Indeed, the main just composes bigger objects from smaller ones:

public final class Main {
  public static void main(String[] args) {
    var vertx = Vertx.vertx();
    vertx.deployVerticleAndAwait(
      new HttpInfrastructure(
        new DurationMatches<>(
          new DeadlineMatches<>(
            new ClassicRuledMatches<>(
              new InMemoryMatches<>(
                new MappedGrids<>(
                  new InMemoryGrids<>(
                    Map.of(
                      new FeatureEqualityPredicate(
                        Map.of(
                          "lang", List.of("it"),
                          "size", List.of("4x4")
                        )
                      ),
                      new LangGrid<>(
                        new FourByFourGrid<>(new SixteenItalianDice()), "it"
                      )
                    )
                  ),
                  LayoutGrid::new
                )
              ),
              Map.of(
                new FeatureEqualityPredicate(
                  Map.of(
                    "lang", List.of("it"),
                    "size", List.of("4x4")
                  )
                ),
                match -> new IfInGrid<>(
                  new IfInVocabulary<>(
                    new FourByFourScore<>(),
                    new DizionarioItalianoIt(WebClient.create(vertx))
                  ),
                  match.grid()
                )
              )
            )
          ),
          Duration::ofMinutes
        ),
        parseUnsignedInt(args[0]),
        args[1]
      )
    );
  }
}
