> When interrupting the background heartbeat thread, `Thread.interrupted();` is used. Actually, `Thread.currentThread().interrupt();` should be used to restore the interruption status. An alternative way to solve is to remove `Thread.interrupted();` since HeartbeatThread extends Thread and all code higher up on the call stack is controlled, so we could safely swallow this exception. Anyway, `Thread.interrupted();`  should not be used here. It's a test method not an action.
