Just to add some credibility to not using this setting. I've also seen
information on Oracle's blogs too:

Hope that helps

G1GC still has an Eden size, however, it's strongly recommended *NOT* to
set the new gen size G1GC and just let it figure it out based on your
target pause time.
Thanks,

If you are using CMS garbage collector then you still have to set the
HEAP_NEWSIZE. With G1GC (new recommended GC) there is no concept of New or
Older generation.
