JVM errors when running minecraft

Question

This is the output I am getting when I am playing minecraft.

Java HotSpot(TM) Server VM warning:
 Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option 'CMSIncrementalMode'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

How can I resolve this?

Edit your Java arguments (Profile Settings) for starting the game and get rid of CMSIncrementalMode (-XX:+CMSIncrementalMode). If your using Java 8 you don't really need any arguments. If you have not installed Java Look here...Install Java 8

The answer still applies; remove the argument for the error in your profile settings. – EODCraft Staff Aug 06 '17 at 01:51
This answer would be so much better if it showed how to go the Java arguments (Profile Settings). – Obsidian Jackal Jan 19 '19 at 05:27
On the Minecraft launcher, those settings are greyed out though. – Obsidian Jackal Jan 21 '19 at 20:26

Nvm, I noticed that I also have check-boxes, but they blend in with the background. – Obsidian Jackal Jan 22 '19 at 02:39

Enter your profile settings and at the bottom make sure JVM Arguments is selected, then delete -XX:+CMSIncrementalMode. That's what worked for me.
