--------------------------------------------------------------
[~Sonia] i checked this issue with the same environment and found out that the
oracle jdk and openjdk's implements of code below is different.
{code}
Files.readAttributes(path, BasicFileAttributes.class)
{code}
That does not relate to the os system except the windows os.
Futhermore, openjdk 1.7 acts the same as oracle jdk.
So, two suggestions to solve this :
1、use oracle jdk 1.8
2、if you want to use openjdk 1.8, you can modify the
TestSFTPFileSystem#testGetAccessTime code like code below：
{code}
@Test
public void testGetAccessTime() throws IOException {
Path file = touch(localFs, name.getMethodName().toLowerCase());
LocalFileSystem local = (LocalFileSystem)localFs;
java.nio.file.Path path = (local).pathToFile(file).toPath();
long accessTime1 = Files.readAttributes(path, BasicFileAttributes.class)
.lastAccessTime().toMillis();
accessTime1 = accessTime1 / 1000 * 1000;
long accessTime2 = sftpFs.getFileStatus(file).getAccessTime();
assertEquals(accessTime1, accessTime2);
}
{code}
[~ste...@apache.org],Any good idea to solve this ?
