[Crash by unknown mod]

I have a 1.5.2 instance of minecraft with 79 mods, and after about 15 minutes of being in-world, it starts lagging regularly, then after 3 or 4 increasingly severe freezes, it crashes.  It is rare to have any crash at all, but I have a crash log from MultiMC.  Here is the first part,  with a mod list and the entire log of what went on before the crash: http://pastebin.com/v8nVLSqp.  Here is the error that actually caused the crash, for convenience:

If anyone could help me track down the problems, that would be fantastic.

 

EDIT: I have also noticed that right before it is about to crash, my computer starts to "freak out."  Usually, the processor runs at about 30% while playing minecraft, but when it crashes, it jumps to about 90%, until it finally gives up and stops.

Oh well

[[Solved]Minecraft Forge Decompile error]

Thanks!  I completely reinstalled both the JRE and the JDK from scratch, as well as added it to the path variable, and the installer ran without a hickup!  Who know what the problem really was, but I'm just glad it works now.

This post is very helpful, it will be good to keep in mind, especially the door timer part...  I may have to adjust some things to deal with that.  Thanks!

[[Solved]Minecraft Forge Decompile error]

Not entirely sure, but it seems like it could be a problem that I don't have anything pertaining to Java in my Path variable?  I'm not sure if I'm looking in the right place, but it says nothing about Java anywhere in it...  This sounds like something I should probably Google to set up?

Thanks for trying!

If you would be willing to do that, I would LOVE to see an explanation of the Villager code!  It would be incredibly helpful for many minecraft-related projects, modding and otherwise.

[[Solved]Minecraft Forge Decompile error]

When I open Java settings in my control panel it pulls up a very simplistic control panel with 4 tabs, General, Java, Security, and Advanced.  Under the Java tab, there is a runtime environment settings dialog box, and under system there is a check next to Java 1.7.0_10, pathed to C:\program files\Java\jre7\bin\javaw.exe

[[Solved]Minecraft Forge Decompile error]

I can read the error.  I found the class in forge\fml\common\cpw\mods\fml\common\asm\transformers.  Is this where it is supposed to be found?

[[Solved]Minecraft Forge Decompile error]

So I take it no-one has any ideas?  I'd really like to get into modding, but at the moment have no idea how to properly de-compile minecraft...

I am trying to use the install.cmd in minecraft forge, but I keep getting this error:

I have tried by installing MCP separately and with Forge, I have re-downloaded and extracted the folder many times, but nothing is working.  I am running windows 8 64 bit and the newest version of Java. Here is the MCP.log:
