Originally, a few places were calling lookupFile/lookupFileStrict, generally giving it this.getClass().getClassLoader().  However, I may have mitigated all of those (as I probably should have) -- I'll double check.

Note that this does eventually trickle down into AggregateClassLoader#getClassLoaders -- the CL arg is prioritized above most others.  But, again, this may no longer be necessary.

And yes, you're correct -- a lot of the .util methods involving CL were pulled in here.  They cannot be static, etc.
