> AbstractServerTest failed on Travis. The Travis link is
> [https://api.travis-ci.org/v3/job/588761985/log.txt]. The error message is as
> follows.
> {code:java}
> 05:53:23.924 [ERROR] Tests run: 2, Failures: 1, Errors: 0, Skipped: 0, Time
> elapsed: 0.113 s <<< FAILURE! - in

> {code}
> The failure can be reproduced by running the test case multi times (until
> failure) locally.
> The failure reason is that the requestStats is shared by two instance of
> TestServer which relies on AutoCloseable interface for connection release. If
> one of the server has been shut down and the anther is not, the assertion in
> the close method can fail. To fix the problem, we can move the assertion out
> of the close method.
