Improvement of sleep in loop

Hi, I found an interesting case in this project.
It has “Thread.sleep()” in a “while(true)” loop. I found some discussion in Stackoverflow and other website. It can be refactored by using a executor service.

Maybe use CountDownLatch.await to automatically awake and shutdown.
