Class JarPatcher

java.lang.Object

com.hloader.patch.JarPatcher

public final class JarPatcher
extends Object

It adds a Launcher-Agent-Class (and Premain-Class) manifest attribute so the JVM itself attaches hloader as a java.lang.instrument agent before the target's own main() runs, then embeds hloader's own runtime (agent, mod loader, Mixin, and their dependencies) into the target jar so the result runs completely standalone via java -jar.
