I am Using Ubuntu 16.04,  
and installed the ES using Deb package ([https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.deb](https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.deb)).

That looks like a pre-release, internal build of JDK9  
Java 9 was officially released in September 2017, and it looks like you have a build from April 2016.

You'll need to get a more recent, supported release of Java 9 (or Java 8).

Thanks,  
Initially i installed jdk 9 using `apt install openjdk-9-jdk`, which was installing the above version.  
after i manually installed jdk 9+181, I am able to run ES.

Thanks for the Help 🙂
