[8u-dev] Request for approval 8131905: (fs) Crash while using WatchService

[Brian Burkhalter]

Please approve this backport request.

Issue:				https://bugs.openjdk.java.net/browse/JDK-8131905
JDK 9 webrev:			http://cr.openjdk.java.net/~alanb/8029516/webrev/
JDK 9 review thread:	http://mail.openjdk.java.net/pipermail/nio-dev/2014-September/002735.html

Changes apply cleanly to jdk8u-dev after path reshuffling from modular source code layout, and the jdk_nio regression tests pass. The JDK 9 patch was approved by its author as suitable for backporting.

Thanks,

Brian
