[8u-dev] Request for review and for approval to backport: 8080115: (fs) Crash in libgio when calling Files.probeContentType(path) from parallel threads

[Ivan Gerasimov]

Hello!

Would you please approve the *almost* direct backport of the fix from 
jdk 9 to 8u?
The patch didn't apply automatically due to renaming of a function.

Bug: https://bugs.openjdk.java.net/browse/JDK-8080115
Jdk9 change: http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/fe002a83ba79
Jdk9 review: 
http://mail.openjdk.java.net/pipermail/nio-dev/2015-August/003257.html

Jdk8u webrev: http://cr.openjdk.java.net/~igerasim/8080115/00/webrev/

The patched jdk was built/tested on all supported platforms.

Sincerely yours,
Ivan
