If we remove the exception here, it would force the default implementation of `LeafCollector#collect(DocIdStream)` to change from this: ```java default void collect(DocIdStream stream) throws IOException { stream.forEach(this::collect); } ``` to that ```java default void collect(DocIdStream stream) throws IOException { stream.forEach(doc -> { try { collect(doc); } catch (IOException e) { throw new UncheckedIOException(e); } }); } ``` which I like less than introducing this functional interface. -- This is an automated message from the Apache Git Service.
