[1.12.2] Forge Crashes While Finishing

[PulseBeat_02]

Hey guys, so I am creating a 1.12.2 modpack that has 450+ mods, but when I run the pack, it crashes around phase 6/7 or 7/7.

Minecraft says that this is no mod problem in the application, so I looked at the crash report.

The crash report said there was an error while loading forge. It goes something like this:

 

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Minecraft Forge (forge)
Caused by: java.lang.ClassCastException

 

Minecraft Forge Version: 14.23.4.2726

 

What does this error mean and how do I solve it?

Here is the full crash report:

Post the debug.log file, not the crash report. It will have more information.

However, you have WAY to many coremods.. should think about killing off those.

The dubug log is way too big to go on pastebin or hastebin. I will attach the text file on dropbox ok.

Oh oops, sorry. I didn't realize that we are not allowed to use dropbox. Sorry about that!

Ok, thanks!
