John Wagenleitner commented on GROOVY-7469:
-------------------------------------------

Running the following in GroovyConsole for version 2.3.10 and current works fine.  Maybe the problem is with how I'm calling the method marked as failing, do you have a self-contained example?

{code}
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
    }
}

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() { this.map = [:] }
        protected Construct(Item item) { this.map = item.map as TreeMap }
    }
}


assert FoodItem.builder().build()
{code}
