Hello all,

I am modding my Minecraft client on version 1.7.2. I am using Forge API. I had troubles with crashing, but finally fixed it. When I now go to create a world, it doesn't load. I think it might have something to do with my JVM arguments. Here is my log when I created the world:

Here are my JVM arguments:

-Xmx3G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

I really want to play Minecraft, so your help is greatly appreciated! Thanks!
