> TestAggregatedLogFormat.testContainerLogsFileAccess test case fails on Windows. The test case try to simulate a situation where first log file is owned by different user (probably symlink) and second one by the user itself. In this situation, the attempt to try to aggregate the logs should fail with the error message "Owner ... for path ... did not match expected owner ...".
> The check on file owner happens at {{AggregatedLogFormat.write()}} method. The method calls {{SecureIOUtils.openForRead()}} to read the log files before writing out to the OutputStream.
> {{SecureIOUtils.openForRead()}} use {{NativeIO.Posix.getFstat()}} to get the file owner and group. We don't have {{NativeIO.Posix.getFstat()}} implementation on Windows; thus, the failure.
