Description

I wrote a test case, but the test result did not meet expectations.

    public void testTryAcquire_negative() {
        RateLimiter limiter = RateLimiter.create(5.0);
        Assertions.assertFalse(limiter.tryAcquire(5000, 0, SECONDS));
    }

Expected Behavior

Test success!

Actual Behavior

Test fail!
