FileType.Cfbf.getAllExtensions() returns null

[ogawaffm]

The following code breaks because FileType.Cfbf.getAllExtensions() returns null instead of String[0]:

    private final static List<String> supportedImageFileTypes = new ArrayList<>();

    static {
        for (FileType fileType : FileType.values()) {
            for (String extension : fileType.getAllExtensions()) {
                supportedImageFileTypes.add(extension.toLowerCase());
            }
        }
    }

As expected, String[0] is returned for FileType.Unknown and FileType.Riff (both of which have no associated extension).
