The NestedField builder relies on the NestedField constructor to validate values, but the builder uses
Integer
for the id value whereas the constructor usesint
.This results in a confusing auto-unboxing related NPE if a field id is not provided to the builder. This PR adds a check prior to the auto-unboxing to provide a reasonable message that the field id is required.
