I'm trying to print a message after the application startup with `@PostConstruct`, but nothing is printed.

```
package dev.renansouza.server;

import javax.annotation.PostConstruct;
import javax.inject.Singleton;

@Singleton
public class ServerService {

    @PostConstruct
    public void print() {
        System.out.println("Hello!");
    }
}

```

I have read that `@PostConstruct` is Lazy. Does this mean that I need to do
something else for this to work?
