There was a problem hiding this comment.
Instead of adding readTailMessages here, it would be more clear to add a thenAccept to the future in readAllExistingMessages(Reader<T> reader).
future.thenAccept(__ -> readTailMessages(reader));Otherwise, if future.complete could be called somewhere else in future, the author might forget to call readTailMessages.
