> Requests reported as pending longer than expected
> -------------------------------------------------
> 
> Key: HTTPCLIENT-2298
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2298
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 5.2.1
> Reporter: Kristijan Postolov
> Priority: Minor
> 
> I was upgrading to the new httpclient5 (more specifically 5.2.1) and noticed an \
> issue where the StrictConnPool does not return accurate stats for the number of \
> pending request. 
> I created an httpClient with connectionRequestTimeout=2000 (2 seconds), \
> responseTimeout=12000 (12s) and maxConnTotal=1 on the \
> poolingHttpClientConnectionManager. The connection request timeout works as \
> expected, when I make a slow request that runs for 10 seconds, and in the meantime \
> I start a second one, the second request will fail after 2 seconds, as there is no \
> available connection. 
> However, after the 2 seconds, when the second connection throws a timeout exception \
> I check the poolingHttpClientConnectionManager.getTotalStats().getPending(), I am \
> still receiving 1 (meaning there is one request that is waiting for a free \
> connection), even though this is not true since the request timed out after the \
> configured 2 seconds. This number gets back to 0, only when the first connection is \
> released (the first 10 second request finishes). I checked the same behavior with \
> the old client (httpclient 4.5.14) and there the pending requests was decremented \
> right after the connection request timeout is reached.
