For several reasons it should be possible to select implementation for the HTTP sampler. I was not able to change the default value which ends up to be None.
As JMeter documentation states:
JMeter sets the Connection: keep-alive header. This does not work properly with the default HTTP implementation, as connection re-use is not under user-control. It does work with the Apache HttpComponents HttpClient implementations.
it might be a good idea to use the HttpClient4 instead of the default implementation.
