>
> The documentation of IndexReaderContext.leaves() states that it returns (for
> convenience) all leave nodes, if the context is top-level (directly got from
> IndexReader), otherwise returns null. This is not correct for
> AtomicReaderContext, where it returns null always.
> To make it consistent, the convenience method should simply return itsself as
> only leave for atomic contexts. This makes the utility method
> ReaderUtil.leaves() obsolete and simplifies code.
