The only thing in that article that was also in playing_colour's list was lambdas.
Which I already conceded as being in Java 8. Not sure what your point is.
You missed immutability, collections, and first class functions.
Java 8 doesn't have immutable collections, nor would I consider Java 8's lambdas to constitute first class functions. Java 8 doesn't have function types, just functional interfaces.
Immutability and collections were two separate list items. And "it doesn't count cause I don't want it to" doesn't really change anything.
