Oleg Kalnichevski commented on HTTPCLIENT-2298:
-----------------------------------------------

[~kristijanpostolov] I am very tempted to close this issue as WONTFIX because 
it is basically a non-issue. Anyway, please provide the exact exception stack 
trace you are getting in case of a connection request timeout. I will take one 
more look at it.

>             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.
