Can I use G1GC garbage collector with jdk8, elasticsearch 6.3 ?  
Some documents say that it it not recommended.  
Is that true?

It's it recommended from 6.5 but with JDK 10. Read details in [https://www.elastic.co/blog/elasticsearch-6-5-0-released](https://www.elastic.co/blog/elasticsearch-6-5-0-released)
