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. Aug 6, 2017 at 1:51
  • This answer would be so much better if it showed how to go the Java arguments (Profile Settings). Jan 19, 2019 at 5:27
  • On the Minecraft launcher, those settings are greyed out though. Jan 21, 2019 at 20:26

    Nvm, I noticed that I also have check-boxes, but they blend in with the background. Jan 22, 2019 at 2:39

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