Steps to Reproduce:

1. Use the latest version 21.1.51
2. runClient / runServer

Description of issue:

cpw.mods.bootstraplauncher.BootstrapLauncher throws an exception that as module named org.objectweb.asm.tree.analysis (9.7) was already on the JVMs module path

asm-analysis 9.5 is introduced by net.neoforged:mergetool:2.0.3 e.g. in the step neoGradleInternalUnhandledNeoFormMinecraftDependenciesForneoFormJoined1.21.1-20240808.144430 while all other parts depend on version 9.7

Even the latest versions of mergetool https://maven.neoforged.net/releases/net/neoforged/mergetool seem to depend on 9.5

There is an "ignoreList" system property used in BootstrapLauncher , but I dont know how to modify it.
