[Ping] Re: 8249703: test/jdk/java/io/File/GetXSpace.java fails on macos

[Brian Burkhalter]

Hi Naoto,

Good point. Here’s an updated version: http://cr.openjdk.java.net/~bpb/8249703/webrev.01/. The number of blocks is not available via a dedicated API call and so has to be calculated.

Thanks,

Brian
