Crash about etil-minecraft-flags

[etil2jz]

It's not a crash, you're using GraalVM CE instead of EE, some flags are part of the EE edition.
Remove each flag that your GraalVM installation says Error parsing Graal options: Could not find option …… and it'll start.

Okay, I modified the 12GB and under one. Maybe edit the README.md to include this?

Hi, there are performance boost in EE instead of CE?

Yes, far more Graal flags to use for compiler optimization
