[MCL-8753] Legacy: Linux: JVM CMSIncrementalMode Error

When launching Minercaft java edition on linux launches the error:
"Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option 'CMSIncrementalMode'"
If I proceed with the elimination of one or both of the JVM arguments the following error is launched:
"Error: the main class was not found or loaded
Caused by: java.lang.ClassNotFoundException:"

You are using Java 9, which is a very tough version of MC to work on although some may expierience higher fps. Anyway, to fix this, Go to your launcher, click Launcher options, and go to the profile you are using, and open "JVM Arguments." Search for "-CMSIncrementalMode" and erase it. You are good to go!

This is a delicate issue, since the old launcher is only minimally supported, and a Java 9 compatibility may not fall into the category of important issues.

Given that the officially supported Java version is still 8 and nowadays we're providing very minimal support for the legacy Launcher, we won't add this bug to our backlog at this time.
