Dear All,
With the help of SAP we were able to find a work around for this issue and switch to http instead of using https , like i had mentioned before changing the parameter /sapstartsrv/httpsconnection = true to false was not taking affect even after restarting SUM and restarting java ( including killing of old sapstartsrv and clean ipc)
SAP requested for the file SharedInputCatalog.xml which is present in ../../SUM/sdt/data and changed a parameter "useHttpsForSapControlConnection" to false
Best Regards,
