[jira] [Created] (HTTPCLIENT-2107) PoolingHttpClientConnectionManager unsafe volatile field access

Carter Kozak created HTTPCLIENT-2107:
----------------------------------------

             Summary: PoolingHttpClientConnectionManager unsafe volatile field access
                 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


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.
