I just can't see, how you'd make Class.forName(...) throw your
pre-allocated exception rather than a new one.

If anything were to be changed in forName(), then it might
rather be offering a variant that returns null instead of 
throwing an exception.  But then again, I think, this particular
scenario(*) is rare enough that it doesn't really matter.

(*): namely the scenario of bulk-classloading requiring a cheap
fail-path.
