[jira] [Created] (HTTPCORE-351) BasicHttpContext#clear() Should Not Be Used

James Leigh created HTTPCORE-351:
------------------------------------

             Summary: BasicHttpContext#clear() Should Not Be Used
                 Key: HTTPCORE-351
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-351
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore NIO
    Affects Versions: 4.3, 4.2.5
            Reporter: James Leigh
             Fix For: 4.3.1


HttpAsyncService.State.reset() should not call clear(), but instead initialize a new (empty) context object for use with sequent requests.

Since HttpCore-nio is expected to be used in a multi-threaded environment, there is not guarantee that when exchange is over, the request/response is not still being processed (in another thread). Consider the situation when the client closes the TCP connection before the response is complete or when the response headers are ready, but the response entity is still being produced. In these situations clearing the HttpContext may have adverse effects in other threads that are still processing the request/response.
