> Affects Versions: 0.21.0

>
> Unit tests are failing on windows due to a problem with rename.
> The failing code is around line 520 in FSImage.java:
> {noformat}
> assert curDir.exists() : "Current directory must exist.";
> assert !prevDir.exists() : "prvious directory must not exist.";
> assert !tmpDir.exists() : "prvious.tmp directory must not exist.";
> // rename current to tmp
> rename(curDir, tmpDir);
> // save new image
> if (!curDir.mkdir())
> throw new IOException("Cannot create directory " + curDir);
> {noformat}
> and seems related to some open file or directory
