Re: Minecraft Forge java.lang.reflect.InvocationTargetException

Hi Alastair,

Yes, unfortunately I've kind of given up on this. The code relies on HotSpot implementation details like class loading ordering/timing and stack traces.

It is possible to get to the main menu by filtering some IKVM specific stack frames from the stack traces, but then it crashes after trying to start the game.

It is also hard to debug because of the (de)obfuscation and dynamic patching that it is doing.

Regards,
Jeroen
