# Here's the fix for the problem of the request futures not being cancelled
during the client shutdown [1]
# I am not sure about the original problem though. What I see is that the mock
server _fails_ to establish a connection. It basically does not respond to the
connection request at all. Eventually the request future correctly timeout and
the test passes for me.

{noformat}
One set a shorter connect timeout by configuring the connection manager
{code:java}
private CloseableHttpAsyncClient buildClient() {
return HttpAsyncClients.custom()
.setConnectionManager(PoolingAsyncClientConnectionManagerBuilder.create()
.setDefaultConnectionConfig(ConnectionConfig.custom()
.setConnectTimeout(Timeout.ofSeconds(15))
.build())
.build())
.build();
}
{code}
As far as I can tell HttpClient works correctly.

> Key: HTTPCORE-777
> URL: https://issues.apache.org/jira/browse/HTTPCORE-777
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore
> Affects Versions: 5.3.3
> Reporter: Oleksandr Kriuchenko
> Priority: Major
>
> There seems to be an issue with async http client request execution:
> if connection is closed during request execution then the future
> returned by the CloseableHttpAsyncClient.execute never completes.
> Please find a test setup to reproduce the issue (along with the
> conditions description under which the issue reproduces) in
> [https://github.com/oleksandr-kriuchenko-lohika/httpcore5-issue]
