I am trying to install 6.2.1 in a windows 2102 server. Elasticsearch service starts successfully if i start via the command line but when i install it as a windows service its failing to start. After investigating the logs it was showing an error in the stderr file as 'Unrecognized option: -server' so i disabled this option in the jvm.options file and reinstalled the windows service again and it started working. Can someone explain if this '-server' setting is required for running this in a windows machine.
I also compared the values between 5.5.2 and 6.2.1 using the GUI property manager and i could see the '-server' option is missing in the 5.5.2 version eventhough the jvm.options file has this value enabled.
My concern is around performance by not setting this value as explained here https://www.elastic.co/guide/en/elasticsearch/reference/current/_client_jvm_check.html
Any pointers are welcome.
