> ---------------------------------------------------------------
>
> Key: HTTPCLIENT-2107
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2107
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 5.0.1
> Reporter: Carter Kozak
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> PoolingHttpClientConnectionManager assumes subsequent volatile reads on
> validateAfterInactivity and defaultSocketConfig result in the same value,
> which can result n incorrect assumptions or even null pointer exceptions.
> We should read a snapshot to a local variable, and reuse the local snapshot.
