jobconf_history.jsp is not showing job configs in case of retired jobs

jobconf_history.jsp is not showing job config for retired jobs, even job id mentioned on this page is wrong. As per mapreduce code all this information is calculated from logFile param passed to these jsp, which flows form jobtracker.jsp -> jobdetailshistory.jsp -> jobconf_history.jsp as shown below.
