It would be good (but not necessary!) to disclose the meaning of 'default value'. It is not necessary because there is a link to 'empty(...)' method so user could understand that default value is zero/null/void. It would be good to use link in the reference "empty(methodType(type))" and "explicitCastArguments(constant(Object.class, null), methodType(type))" because it's much more easy to access them using link.
