Subject: [PATCH] [Lombok] RequiredArgConstructor : private or @NonNull fields

Example of Streamable using @RequiredArgConstructor(staticName = "of") won't generate a static "of" if the field streamable is not final or at least with @NonNull.

It will generate an java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class [...] Products
