json itd creating incorrect code in controller_json.aj file when Entity Id field is not named "id"

When creating a JSON-ed Controller for a JSON-ed Entity where the @Id field is not named "id", the controller_roo_controller_json.aj file creates invalid code. I have attached the project for review (via roo backup).

Here are the steps in the log.roo file:

jpa setup --database H2_IN_MEMORY --provider HIBERNATE
entity jpa --class ~.domain.Product
field string --fieldName productName --column productname --notNull true
// I manually added the @Id annotation to the productName field in the Product file
