>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 1.2.0, 1.1.1
>         Environment: Win 10 with Oracle JDK 1.8.0_121 on NTFS
>            Reporter: Puspendu Banerjee

> Nifi is failing to start due to IOException originating from 
> FileSystemRepository during calls to {code:java}
> Files.getFileStore(path).getTotalSpace();
> Files.getFileStore(path).getUsableSpace();
>  {code} with a read-access denied status.
> It looks like a buggy JDK implementation as on the other hand the following 
> code is yielding result:
> {code:java}
> path.toFile().getTotalSpace();
> path.toFile().getUsableSpace();
> {code}
> Interestingly, the both of the codes are yielding same results for C:\ or 
> System Drive.
> *sample*
> {code:java}
> import java.io.File;
> import java.io.IOException;
> import java.nio.file.Files;
> import java.nio.file.Path;
> import java.nio.file.Paths;
> import java.util.Arrays;
> import static java.lang.System.out;
> public class Blah {
>     public static void main(String [] args) throws IOException{
>         String [] _paths= {"D:\\workspace\\nifi", "c:\\Program Files"};
>         final float divisor=1024 * 1024 * 1024f;
>         for(String _path : _paths) {
>             try {
>                 Path path = Paths.get(_path);
>                 out.println(path.toFile().getTotalSpace() /divisor  + "GB");
>                 out.println(Files.getFileStore(path).getTotalSpace()/divisor 
> +"GB");
>             }catch (Exception ex){
>                 ex.printStackTrace();
>             }
>         }
>     }
> }
> {code}
