[jira] [Updated] (HTTPASYNC-64) Race condition using
CachingHttpAsyncClient
[ https://issues.apache.org/jira/browse/HTTPASYNC-64?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleg Kalnichevski updated HTTPASYNC-64:
---------------------------------------
Fix Version/s: 4.0.1
> 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".
