I already purchased the first edition: Java 8 In Action. I am not very sure if most of the Java 8's content of this 2nd edition is just repeated from the 1st edition.

Besides the addition of Java 9's new features, any other improvements, e.g. better explanations, better overall picture of the combination of Java 8 and 9's features, etc., that is worth buying this 2nd edition, instead of looking elsewhere for a book about Java 9?
