Please review at your convenience: Issue: https://bugs.openjdk.java.net/browse/JDK-8087288 Patch: http://cr.openjdk.java.net/~bpb/8087288/webrev.00/
The root cause of this problem is essentially the same as that of https://bugs.openjdk.java.net/browse/JDK-8081843 and the proposed fix is likewise similar: on Mac OS X replace statvfs64() and struct statvfs64 with statfs() and struct statfs, respectively, and f_frsize with f_bsize. Thanks, Brian
