We now detect withher methods (withId(…)) that create a new object instance that contains the new property value. We support those wither methods to create new object instances from property updates. Classes following a wither pattern declare a withXXX(…) method that accepts the property value and return a new, instance of its own type associated with the property value. Along with this change we removed the ability to update final fields that worked by accident using reflection.
class ValueClass {
@Wither String id;
}
class ValueClass {
final String id;
ValueClass withId(String id) {
return new ValueClass(id);
}
}
