BUG FIX: Elasticsearch is not working and closes immediately

I tries re-installing Elasticsearch 6.3.0 on my local server, and installed Java JDK, the most recent one, then when I try to start the Elasticsearch from installation folder/6.3.0/bin/elasticsearch.exe the cmd screen opens and immedietely closes. Here is the error : Unrecognized VM option 'UseConcMarkSweepGC'

So, Here are the steps I have made, 

1. I started to run the file from within the cmd.


2. This showed me an error : Unrecognized VM option 'UseConcMarkSweepGC'


3. The reason for this is that VM option is removed from the recent JDK,


4. So, The solution would be to dowbgrade the Java JDK.


5. NOTE: You can have two versions on the Java JDK on your machine.
