Refine implicit @ConfigurationProperties handling with records

[sdeleuze]

As reported here this works:

@ConfigurationProperties("servers")
@ConstructorBinding
public record ServersConfiguration(ServerConfiguration server) {
  public record ServerConfiguration(int port) {
    public ServerConfiguration{
      System.out.println("Port: " + port);
    }
  }
}

While this does not work:

@ConfigurationProperties("servers")
public record ServersConfiguration(ServerConfiguration server) {
  public record ServerConfiguration(int port) {
    public ServerConfiguration{
      System.out.println("Port: " + port);
    }
  }
}
