Hi,
After initialising my new dimensions/planets, any world, new or otherwise, appears to crash with this log:

Before this, my mod loaded with one gigabyte of RAM and half the current permgen size, so I'm pretty sure that it's the dimensions.
The mod that includes the dimensions is SpaceAgePlanets, and the other mods whose source I have in my dev environment (ie the ones that I'm working on) are SpaceAge and WarpDrive.
If required, I can give source code for any one of my dimensions.
Thanks,
SkylordJoel
