Hi, Please review this fix for a bug in the stream takeWhile operation:
http://cr.openjdk.java.net/~psandoz/jdk10/JDK-8193856-takeWhile-incorrect-results/webrev/ <http://cr.openjdk.java.net/~psandoz/jdk10/JDK-8193856-takeWhile-incorrect-results/webrev/> The flatMap operation is currently aggressive and does not detect if a downstream operation may or has cancelled processing, and will push all of it’s elements downstream. Short-circuiting operations should be guarded against such behaviour but unfortunately takeWhile was not guarded. — Separately i plan to figure out a way to ensure flatMap operations become less aggressive if there are short-circuiting downstream operations. This may increase efficiency and also allow support for flat map results that are infinite. Paul.
