The different code path that existed prior to this change would omit the calls to `onFieldValuesInfo` when an `UnresolvedTypeException` occurred, and that causes a thread leak similar to an older issue for unhandled exceptions graphql-java#2068 - that is, once a type cannot be resolved, the deeper batches from other (successful) branches are never dispatched. Since we are just adding an error in the cases of `UnresolvedTypeException` and try to set the value to null, this only needed a small refactoring to make it similar to when the value is actually null.

There was a problem hiding this comment.
I had a look at this in the complete code. I can see that the value as not being completed into a CF and hence this would intere with the completion of data loaders and so on.
