> Key: HTTPCLIENT-2301
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2301
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 5.2.1, 5.3-alpha1
> Environment: JAVA 18
> kotlin 1.7.22
> Ubuntu 22.04 x64
> Reporter: Pierre N.
> Assignee: Arturo Bernal

> Attachments: test.kt

> BasicHttpClientConnectionManager doesn't handle request timeout correctly and
> return the response of a previous request.
> The unit test below should output:
> {quote}
> http://localhost:41751/1 -> 1
> http://localhost:41751/2 -> java.net.SocketTimeoutException: Read timed out
> http://localhost:41751/2 -> java.net.SocketTimeoutException: Read timed out
> http://localhost:41751/3 -> 3
> http://localhost:41751/3 -> 3
> http://localhost:41751/3 -> 3
> {quote}
> But instead it returns:
> {quote}
> http://localhost:33875/1 -> 1
> http://localhost:33875/2 -> java.net.SocketTimeoutException: Read timed out
> http://localhost:33875/2 -> java.net.SocketTimeoutException: Read timed out
> http://localhost:33875/3 -> java.net.SocketTimeoutException: Read timed out
> http://localhost:33875/3 -> 2
> http://localhost:33875/3 -> 3
> {quote}
> As you can see it returns 2 when requesting the uri /3 which returned 3.
> Also it timeout on the first request to /3 while it shouldn't.
> Replace with PoolingHttpClientConnectionManager() and it works as expected.
> Kotlin unit test to reproduce :
> {quote}
