> Our tree-building code is a bit more than this, but I was able to trim back and still produce the run-time exception:
> {code:groovy}
> def test(... attributes) {
>     List one = [
>         [id:'x', options:[count:1]]
>     ]
>     List two = attributes.collect {
>         def node = Collections.singletonMap('children', one)
>         if (node) {
>             node = node.get('children').find { child -> child['id'] == 'x' }
>         }
>         // inferred type of node must be something like Map<String,List<...>>
>         [id: it['id'], name: node['name'], count: node['options']['count']]
>         //                                        ^^^^^^^^^^^^^^^ GroovyCastException (map ctor for Collection)
>     }
>     two
> }
> test( [id:'x'] )
> {code}
> Changing the type of "one" from "List" to "def" stops the madness.
