Hi folks, Looking for a review for this change.
Basically https://bugs.openjdk.java.net/browse/JDK-8135305 abandoned the old TCP echo isReachable check in favour of Windows' ICMP calls on supported platforms. Unfortunately it turns out that Windows 10's new App Containers don't actually allow access to these calls. This fix adds a check to see if access to those calls is allowed on those supported platforms and if not, falls back to the old TCP method. http://cr.openjdk.java.net/~robm/8150234/webrev.01/ -Rob
