Description

My directory tree:

~/ioutils> ls -lhR
.:
total 20K
drwxrwxr-x 2 jorge jorge 4.0K Dec  2 14:54 empty/
drwxrwxr-x 2 jorge jorge 4.0K Dec  2 14:54 not-empty/
-rw-rw-r-- 1 jorge jorge    5 Dec  2 15:02 text.txt

./empty:
total 0

./not-empty:
total 12K
-rw-rw-r-- 1 jorge jorge 5 Dec  2 14:54 text.txt

When I execute:

File baseDir = new File("/home/jorge/ioutils");
IOFileFilter emptyDirectoriesFilter = FileFilterUtils.and(
  DirectoryFileFilter.DIRECTORY, 
  EmptyFileFilter.EMPTY
);
FileUtils.listFilesAndDirs(baseDir, emptyDirectoriesFilter, TrueFileFilter.TRUE);

I obtain:

[/home/jorge/ioutils, /home/jorge/ioutils/not-empty, /home/jorge/ioutils/empty]

Issue: /home/jorge/ioutils/not-empty directory is included in the result.

But If I execute

baseDir.list(emptyDirectoriesFilter);

the correct result includes /home/jorge/empty directory.
