Title: Change cache by LRU cache to fix memory leak

We've change the cache by an instance of simple-lru cache to fix a memory leak,
We've also change
str = new StringDecoder('utf8').write(str);
by
str = new StringDecoder('utf8').write(str.toString());
to fix test error

Please tell me if it's some thing wrong

Regards.
