Win 10 with Oracle JDK 1.8.0_121 on NTFS
Description
Nifi is failing to start due to IOException originating from FileSystemRepository during calls to
Files.getFileStore(path).getTotalSpace(); Files.getFileStore(path).getUsableSpace();
with a read-access denied status.
It looks like a buggy JDK implementation as on the other hand the following code is yielding result:
path.toFile().getTotalSpace(); path.toFile().getUsableSpace();
Interestingly, the both of the codes are yielding same results for C:\ or System Drive.
sample
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(); } } } }
