[forge-dev] Weird error again....

Ok well, once I turned on logging I was able to figure out the root cause,
but I don't know exactly why yet. I'm assuming that the stack trace is
fairly obvious. The question is. "What is the correct way to resolve it?"
Side note: I really need to add a logging toggle in Forge itself, but it
would need to go into the launcher, just haven't gotten around to it yet.
Currently, one needs to edit the build to enable logging *gulp* (Search for
"LOGGING") in the source and you'll see what I mean :/ That might be my
tomorrow (in addition to working on this.) I'm going to be cutting a Beta5
very soon because of some issues in the recent Beta4.
