I think the type check for `@KeyId` breaks if the key is generic. I was trying this out and got:
```
java.lang.IllegalArgumentException: CombinerDoFn, @OnTimer onTriggerTimer(BoundedWindow, WindowedKey, CombiningState, CombiningState, ValueState, CombiningState, BagState, OutputReceiver): @Key argument is expected to be type of WindowedKey<K>, but found class WindowedKey
```
