If I try to execute the following code:

       public static void main(String[] args) {
           try {
               File file = File.createTempFile("tmp", null,
                   new File(System.getProperty("user.dir")));
               file.deleteOnExit();
               System.out.println("File exists = " + file.exists());
               System.out.println("Total space " + file.getTotalSpace());
               System.out.println("Free space " + file.getFreeSpace());
               System.out.println("Usable space " + file.getUsableSpace());
           } catch (Exception e) {
               System.out.println("Unexpected exception "+ e);
           }
       }

on SOLARIS platform, I get the output:
File exists = true
Total space 35833200640
Free space 5932088320
Usable space 5573756928

on WINDOWS platform, I get the following:
File exists = true
Total space 0
Free space 0
Usable space 0

File was physically created on disc in both cases, all needed permissions were granted. Such behaviour seems to be strange.

JCK tests fail on windows because of this issue:
