IllegalStateException with async REST service

I am seeing the below `IllegalStateException`s in our integration tests with an async REST service and so far we don't have any reliable reproduction.

```

The REST service code is [here](https://github.com/prestodb/presto/blob/master/presto-main/src/main/java/com/facebook/presto/server/TaskResource.java#L234), and the class where we do the async resume call is [here](https://github.com/airlift/airlift/blob/master/http-server/src/main/java/io/airlift/http/server/AsyncResponseHandler.java#L102) (in these stack traces `TestingAsyncResponseHandler` resumes the request, but it's the exact same code with `AsyncResponseHandler`). We are using Jersey 2.22.2 and Jetty 9.4.7.v20170914.

So far I have been investigating this issue with the Jetty team, at the same time I also wanted to get the opinions of Jersey experts and see whether this can be a Jersey issue. Any input is greatly appreciated.
