Commit 5678143786e89ce41df9acefae4a4bdf25f16519 in geode's branch 
refs/heads/feature/GEODE-6321 from zhouxh
[ https://gitbox.apache.org/repos/asf?p=geode.git;h=5678143 ]

GEODE-6321: This is race caused by not enough SLOP time (it could use up to 
300ms). The next test testShutdown2 used 3 seconds sleep,
but verify at least run for 2 seconds. Apply the same design to resolve the 
race.
The logic is already verified in assertTrue(ex.awaitTermination())


> ScheduledThreadPoolExecutorWithKeepAliveJUnitTest's testShutdown() has 
> invalid expectation

> reproduced following failure:
> org.apache.geode.internal.ScheduledThreadPoolExecutorWithKeepAliveJUnitTest > 
> testShutdown FAILED
>     java.lang.AssertionError: Shutdown did not wait to task to complete. Only 
> waited 3850
>         at org.junit.Assert.fail(Assert.java:88)
>         at org.junit.Assert.assertTrue(Assert.java:41)
>         at 
> org.apache.geode.internal.ScheduledThreadPoolExecutorWithKeepAliveJUnitTest.testShutdown(ScheduledThreadPoolExecutorWithKeepAliveJUnitTest.java:226)
> {noformat}
> The root cause is:
> The test detected the shutdown finished within 10 seconds as expected. But it 
> also expected it to finish longer than 4 seconds. This is an invalid 
> expectation. Usually it did finish after 4 seconds, but on some running VMs, 
> it finished earlier (such as 3850 ms this time).
