6937320: (fs) Path getFileStore().type() does not return correct type of file store on Linux

[Bernd Eckenfels]

Hello,

The bug title is a bit misleading, can that be fixed before it shows up in the commit?

Gruss
Bernd

Betreff: 6937320: (fs) Path getFileStore().type() does not return correct type of file store on Linux

https://bugs.openjdk.java.net/browse/JDK-6937320
http://cr.openjdk.java.net/~bpb/6937320/webrev.00/

The failure addressed here occurred on Linux when trying to obtain the FileStore of “/“ which on some misconfigured systems was “rootfs” instead of the actual device due to duplicate entries for “/“ in /proc/mounts with the rootfs entry being first. The change is to attempt to recognize an actual device path, e.g., /dev/sda1, in the entry and to use the first non-path entry, e.g., rootfs, only if a path-like entry was not encountered first.

Thanks,

Brian
