> If we want to use immutable objects, we should use Java Records. We still do not have Valhalla ready. The developers often do not understand Java Memory Model and there is no guarantee that they would not make a mistake when they update any immutable object. The developers usually would not understand why ConcurrentLinkedQueue is preferable over ArrayList and `List.copyOf()` is ideal https://docs.oracle.com/javase/10/docs/api/java/util/List.html#copyOf(java.util.Collection), and so we should use `List.copyOf()` which means that we should switch the project to Java 10 - bad luck! Nobody would accept Java 10, I guess. > > The immutable object should be fetched with data via a builder in constructor. `MavenProject and MavenProjectBuilder composition` > > ``` > public record MavenProject(MavenProjectBuilder builder) { > > MavenProject { > dependencies = List.copyOf(builder.getDependencies()); > ... > ... > ... > } > } > ``` Have you had a look at the generated code or are those just general comments about java records / immutable objects ? -- This is an automated message from the Apache Git Service.
