ping @xintongsong For scheduling runnable with some delay, I find it is hard to check that the delay is exactly the right number. for example, we schedule a runnable with 1 second delay, and after exactly 1 second, the runnable is always not triggered. So I add extra 50ms delay to check whether the runnable is triggered. I am not very sure it is bug or just because it takes some time for the Executor to execute the runnable. For scheduling runnable with different TimeUnit, I just checked minute/second/millisecond. For microsecond and nanosecond, i am afraid the executor can not be that accurate. For hour and day, it just take too much time to finish the test. -- This is an automated message from the Apache Git Service.
