net.neoforged.fml.startup.DevAgent

public final class DevAgent
extends Object

Our javaagent which we attach to the JVM to be able to add opens/exports to modules when the receiving modules aren't defined at boot time, and we can't use JVM CLI args. It's also useful for JUnit scenarios, where adding JVM arguments for IDEs is very annoying.
