> Follow up from GROOVY-9033.  Consider the following:
> {code:groovy}
> abstract class State<H extends Handle> {
>     // Why not return HandleContainer<H>? I can't really say.
>     def <T extends Handle> HandleContainer<T> getHandleContainer(key) {
>     }
> }
> class HandleContainer<H extends Handle> {
>     H handle
> }
> interface Handle {
>     Result getResult()
> }
> class Result {
>     int itemCount
>     String[] items
> }
> List<String> getStrings(State state, List keys) {
>     keys.collectMany { key ->
>         List<String> strings = Collections.emptyList()
>         def container = state.getHandleContainer(key) // returns HandleContainer<Object> not HandleContainer<Handle>
>         if (container != null) {
>             def result = container.handle.result
>             if (result != null && result.itemCount > 0) {
>                 strings = Arrays.asList(result.items)
>             }
>         }
>         strings
>     }
> }
> {code}
