Description

After updating commons-io from 2.8.0 to 2.9.0 the method FileUtils.iterateFiles also returns directories.

Codeexample:

        final File directory = new File(FileUtils.getTempDirectory(), "TEST");
        directory.mkdir();
        new File(directory, "TEST").mkdir();
        new File(directory, "test.txt").createNewFile();

        final IOFileFilter filter = new WildcardFileFilter("*", IOCase.INSENSITIVE);
        for (final Iterator<File> itFiles = FileUtils.iterateFiles(directory, filter, null); itFiles
                .hasNext();) {
            final File file = itFiles.next();
            System.out.println(file.getAbsolutePath());
        }

result in version 2.8.0:

/tmp/TEST/test.txt

result from version 2.9.0:

/tmp/TEST/test.txt
/tmp/TEST/TEST

iterateFiles shouldn't return directories.
