Hongyuan Li commented on HADOOP-14486:
--------------------------------------

[~Sonia] this change work with opendjk 1.7 and oracle 1.8 as well.The oracle jdk and openJDK
1.7's Files.readAttributes(path, BasicFileAttributes.class) method get time in second accuracy,
the value of which is like XXXXX000,but openJDK 1.8 and WindowFileAttributes don't.

[~stevel@apache.org] i will submit the patch here soon.
my test environment lists below:
os : ubuntu-14.04.5-server-amd64
jdks:
{code}
 java-7-1.7.0_131(java version "1.7.0_131", OpenJDK Runtime Environment (IcedTea 2.6.9) (7u131-2.6.9-0ubuntu0.14.04.2)
 OpenJDK 64-Bit Server VM (build 24.131-b00, mixed mode));
{code}
{code}
        oracle jdk1.8.0_131(java version "1.8.0_131",  Java(TM) SE Runtime Environment (build
1.8.0_131-b11), Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)) ;
{code}
{code}
     openjdk version "1.8.0_111"(openjdk version "1.8.0_111",OpenJDK Runtime Environment (build
1.8.0_111-8u111-b14-3~14.04.1-b14),OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode))
{code}

using {{openjdk version "1.8.0_111"}} will encounter this problem.
