BufferedReadernewBufferedReader(Path path)
This method is able to determine whether a file is GZipped and return a BufferedReader in any case 
BufferedReader br = null;
if (path.toFile().getName().endsWith(".gz")) {

} else {
    br = Files.newBufferedReader(path, Charset.defaultCharset());
return br;
