use jk module

submit some data with post method ,but  "Bytes received" always show zero

see source file ,JkCoyoteHandler.java ,in "inovke" method

 public int invoke( Msg msg, MsgContext ep )
        throws IOException {
        if( ep.isLogTimeEnabled() )
            ep.setLong( MsgContext.TIMER_PRE_REQUEST, System.currentTimeMillis());

        Request req=ep.getRequest();
        Response res=req.getResponse();

        if( log.isDebugEnabled() )
            log.debug( "Invoke " + req + " " + res + " " + req.requestURI().toString());

        res.setNote( epNote, ep );
        ep.setStatus( MsgContext.JK_STATUS_HEAD );
        RequestInfo rp = req.getRequestProcessor();
        rp.setStage(Constants.STAGE_SERVICE);
        try {
            adapter.service( req, res );
        } catch( Exception ex ) {
            log.info("Error servicing request " + req,ex);
        }
        if(ep.getStatus() != MsgContext.JK_STATUS_CLOSED) {
            res.finish();
        }
      
        req.recycle();         
        req.updateCounters();   //see this line
         res.recycle();
        ep.recycle();
        if( ep.getStatus() == MsgContext.JK_STATUS_ERROR ) {
            return ERROR;
        }
        ep.setStatus( MsgContext.JK_STATUS_NEW );
        rp.setStage(Constants.STAGE_KEEPALIVE);
        return OK;
    }

 the request object recycled,the "byteRead" property must be set to zero ,but at the next line ,begin to "updateCounters",this may be a bug
