[9] RFR of JDK-8073078: java/nio/file/FileStore/Basic.java sensitive to NFS configuration

[Brian Burkhalter]

Please review at your convenience.

Issue:	https://bugs.openjdk.java.net/browse/JDK-8073078
Webrev:	http://cr.openjdk.java.net/~bpb/8073078/webrev.00/

Summary: Ignore NoSuchFileExceptions as the store might have been deleted subsequent to creation of the FileStore iterator which is not dynamic.

This change should also fix https://bugs.openjdk.java.net/browse/JDK-8081354 and https://bugs.openjdk.java.net/browse/JDK-8065959.

Thanks,

Brian
