James Leigh commented on HTTPASYNC-64:
--------------------------------------
I kicked the code around for a week and everything behaves normally and the
chaining logic is easier to follow now too!

> Race condition using CachingHttpAsyncClient
> -------------------------------------------
>
> Key: HTTPASYNC-64
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-64
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Affects Versions: 4.0 Final
> Environment: JDK 1.7, macbook pro
> Reporter: Rahul
> Labels: CachingHttpAsyncClient, FutureHttpResponse, concurrency,
> race-condition
> Fix For: 4.0.1
>
>
> Running into a race condition when using CachingHttpAsyncClient. The async
> client at times returns null from the FutureHttpResponse obtained from
> CachingHttpAsyncClient.execute(HttpGet, null)
> In FutureHttpResponse the get() method has the following implementation -
> try {
> getDelegate().get();
> } catch (ExecutionException e) {
> // ignore
> }
> final HttpResponse result = getResponse();
> When the getDelegate().get(); returns, the getResponse() returns null. It
> seems the thread doing the actual request/response processing still hasn't
> called "setResponse".
