Is there a way to include a VM parameter inside a .jar?

Question

I have a game implemented in Java that was having a problem when running too much code from scripts: depending on the script language, the game could have these "hiccups" where the game would freeze for a couple frames every now and then, making the game "jerky" at times.

After some research, I discovered that was happening when the Garbage Collector decided to run. After some more research and testing, I discovered that using the incremental garbage collector (by using the -Xincgc VM parameter) fixed the problem. Yes, I am aware it makes the GC run about 10% slower, but it is the cost I pay.

With that background information, now what I want to do is package the game in a .jar like I have been doing so far, but I know no way of making the application use the incremental GC without using -Xincgc, and I didn't want to create .bat/.sh files where before the user only had to double-click the .jar.

Is there any way to make the .jar run with the incremental GC without needing some kind of loader (.bat/.sh) or wrapper around it? Is there some way to include that parameter in the .jar?

No, there's no way to do that. VM arguments can only be supplied as command-line parameters to JVM invocation: Java Tool
