Hi ,
Can i use the G1GC setting with ES version 7.2.0 which is running with jdk 1.8 ?

Does it has any performance issues for lower java versions or its not even supported for lower version of java as mentioned (commented) in jvm.options file:

G1GC Configuration

NOTE: G1GC is only supported on JDK version 10 or later.

To use G1GC uncomment the lines below.

10-:-XX:-UseConcMarkSweepGC

10-:-XX:-UseCMSInitiatingOccupancyOnly

10-:-XX:+UseG1GC

10-:-XX:InitiatingHeapOccupancyPercent=75
