Jochen Theodorou commented on GROOVY-7469:
------------------------------------------
the code above is missing at least several closing brackets, but also the
constructor for FoodItem. Without the signature of that method it is impossible
to know why he problem happens. The error message itself would also be very
helpful
> ClassCastException in groovy 2.3.10. See description section for more
> information

> Hi Team,
> I'm facing an issue with groovy version 2.3.10. I'm doing the version upgrade
> from 2.2.2 to 2.3.10.
> The existing code is working in groovy 2.2.2 and the same code throws an
> exception (ClassCastException) in groovy 2.3.10.
> //FoodItem Class -- start
> Class FoodItem extends Item
> {
> static Construct builder() {
> new Construct()
> }
> static class Construct
> {
> Item.Construct build
> Construct() {
> build = new Item.Construct() { }
> }
> FoodItem build() {
> new FoodItem (build.map) // This line throws the classcastexception
> }
> }
> //FoodItem Class -- End
> // Item class -- start
> abstract class Item
> {
> protected TreeMap map
> protected Item() {
> this.map = [:]
> }
> protected Item(TreeMap map) {
> this.map = [:]
> if (map != null) {
> this.map = map
> }
> }
> protected Item(Map map) {
> this.map = [:]
> if (map != null) {
> this.map = new TreeMap(map)
> }
> }
> TreeMap getMap() { this.map }
> abstract protected static class Construct {
> protected TreeMap map
> protected Construct() {

> // Item class -- End
