MC 1.7.10 // JAVA 21+ FIX

makes fisk's mod actually boot on modern java so i can play

tl;dr why it crashes

fisk's mod calls jdk.nashorn for hero JS packs. oracle deleted nashorn in java 15. https://openjdk.org/jeps/372 and game goes boom:

Caused by: java.lang.ClassNotFoundException: Class bytes are null for jdk.nashorn.api.scripting.NashornScriptEngineFactory

what i did instead of rewriting fisk's mod

shaded standalone org.openjdk.nashorn:nashorn-core into the jar
wrote a lazy ASM transformer to catch com.fiskmods.heroes.* at boot
replaces all string/type refs from jdk.nashorn -> org.openjdk.nashorn in memory so it just works

requirements or whatever

1.7.10 / Forge 1614+ / Java 21-25 (LWJGL3ify) / Fisk's Superheroes 2.4.0+

works on both client and server (just put it in /mods).

install

drop jar in mods/
launch game
profit

why this exists

was working on advanced lightsabers rewrite structure generation, got annoyed, made this in like 20 minutes to procrastinate. also rewriting transformers mod eventually. maybe.
