> The new RegexFileFilter.accept(Path, BasicFileAttributes) uses the full path for matching. When this filter is used in combination with FileUtils.listFiles(File, IOFileFilter, IOFileFilter), then it will not match anything if a path separator is not part of the pattern.
> The following small program will list all files when used with version 2.8.0 and nothing when used with version 2.9.0:
